China Exploring Venus

Later this year, a box-sized module will be carried into orbit by a rocket. This will be the first step towards a Chinese space station. Around 2013, China is in works of launching a lunar probe that will release a rover on the moon. Also, the country is striving to put a man on the moon somewhere around 2020. Some experts are worried about the fact that China is slowly starting to get ahead of the U.S. They want to preserve the country’s reputation of having a prestigious space science program. Although China is still a few big steps behind the U.S. in space technology and experience, what China does not lack is the knowledge of how to get financial resources. The U.S. is already in debt for so many other things that the budget is highly strained for space programs, unlike China. China is at advantage because of their 5 year plans that allows them to think ahead and plan accordingly. Back in 2003, China became the third country, following the U.S. and Russia, to send an astronaut into space on its own. Three years later, China sent its first probe to the moon. In 2008, China had its first spacewalk. China’s space station is supposed to open in 2020, which is the same year that the International Space Station is scheduled for closing. Therefore, the U.S. and its partners must come up with a replacement, or else China will have the only human presence in the sky. China’s space lab module, which is supposed to be launched later this year, will test docking procedures for the space station. China’s space station will be much smaller than the International one that is shared by U.S., Russia, Canada, Japan and 11 European countries. Furthermore, China’s space advancements are greatly significant for the people of China. They see this as a national pride. Some aspects of China’s program, especially some dangerous incidents that have happened in the past, are alarming American officials and others who fear that certain moves could set off a race to militarize space. The U.S. is hesitant to cooperate with China in matters of space because the program is run by the military. China, however, insists that the program is peaceful. The country argues that this new space endeavor is not for military purposes; rather, it is for advancing in space technology and new discoveries.

In addition to China, Russia has been in discussion about a possible mission to Mars and building a base on the moon. A time frame, however, has not been set yet. India also has plans for its first manned space flight to occur in 2016. The U.S. has a “been there, done that” attitude regarding landing on the moon. They have other plans lined up for the future. Furthermore, China’s future in regards to space will be exciting to watch. They plan to send a man on the moon and a lunar probe by 2025 at the latest.

The Color of Venus

Planets have their specific colors as a cause of the materials that they are made up of and based on how their surface and atmosphere absorbs or reflects light from the sun. Venus is completely covered with an atmosphere of 96% thick carbon dioxide and sulfuric acid clouds which give it the appearance of being light and yellowish. It might come to surprise to learn that most of the pictures that you have seen of Venus are probably misleading, according to many astronomers. Many times, astronomers use spacecraft to take pictures of Venus and they use different wavelengths of light in order to point out certain information or features in the atmosphere. These falsified pictures tend to show Venus as being reddish in color, when in actuality it is a yellowish-white colored planet. If looking at Venus with the perspective of having your eyes above the atmosphere, you would see a very bright white and yellow ball lacking any features. This is the reason that the spacecraft photographs Venus using different wavelengths, such as ultraviolet. This way, one can see a few of the different structures in the clouds surrounding the planet. If it was possible to travel to the surface of Venus, we would be able to see brownish-red rocks. The rocks may be similar to the volcanic rocks on our planet; however, the thick clouds on Venus allow very little light to reach the surface. Therefore, everything would look dim with tints of red. It is important to know that the surface of Venus is what its true color is and due to sulfuric acid, Venus has a yellow and white hue. The brightness of Venus can be attributed to its dense atmosphere which helps to reflect sunlight. Sulfuric acid droplets reflect back about 70% of the sunlight.

Moreover, an astronomer looking at Venus from Earth must be mindful of the fact that the Earth’s own atmosphere may affect how Venus appears. Particles of dust, dirt and chemicals may cause the planet to seem to shimmer, sparkle, or change color, as light reflected from Venus travels through Earth's atmosphere. Therefore, at times the planet can seem to be going through certain changes in color and appearance; however, realistically, there are quite a few external attributes that are making it appear that way. In addition, even though it is possible to view Venus through a telescope or binoculars, it is known for giving lots of trouble to those who wish to view it in great detail. This is because Venus is located in a low altitude above the Earth’s horizon. The planet’s brightness also creates a blur for the observer and as mentioned before, its thick and cloudy atmosphere makes the surface features never visible.

How Venus Got Its Name

The celestial bodies have always been subjects of fascination for humankind. From the twinkling stars to the radiant planets, each entity in the vastness of space carries a tale, both scientific and mythological. One such intriguing planet in our solar system is Venus, our 'sister planet' due to its similarities in size and proximity to Earth. But how did Venus come to be known by this name? This article delves into the origins, historical significance, and the mythology associated with the name of the second planet from the sun.

The Ancient Connection

Throughout history, different cultures have observed Venus with keen interest due to its brightness and visibility from Earth. To the ancients, Venus was not just a mere celestial body but held profound spiritual and symbolic significance, serving as both an astronomical marker and a cultural emblem.

Babylonians: The Babylonians named Venus 'Ishtar', their goddess of love, war, and sexuality. To them, the radiant appearance of the planet embodied Ishtar’s ethereal beauty and power. They extensively used Venus’s cycles to mark their calendar and predict significant events.

Mayans: For the Mayans, Venus was associated with the god of war, Kukulcan or Quetzalcoatl. They meticulously recorded the planet’s appearances and movements in the Dresden Codex, one of their sacred texts. The heliacal rise of Venus, where it first becomes visible in the east just before dawn, was considered an important event, often correlating it with warfare, as they believed the planet was a harbinger of conflict and disruption.

Ancient Egyptians: To the Egyptians, Venus was linked to two major deities: Isis, the goddess of fertility and motherhood, and Hathor, the goddess of music, dance, and beauty. The planet's cyclical pattern of disappearing beneath the horizon and re-emerging after some time resonated with the story of Isis and Osiris, signifying rebirth and renewal.

Ancient Greeks: Before understanding that its dawn and dusk appearances were of the same celestial body, the Greeks initially named Venus as two separate entities: Phosphorus (morning star) and Hesperus (evening star). Both were associated with the beautiful goddess Aphrodite. The luminescent quality of Venus in the sky echoed the tales of Aphrodite’s unparalleled charm and allure.

By exploring the multifaceted perspectives of various ancient cultures, we can comprehend how Venus was more than just a sparkling dot in the sky. It was a vessel of stories, beliefs, and traditions, deeply woven into the fabric of ancient societies.

The Roman Influence

It was the Romans, however, who provided the planet with the name by which we recognize it today. Deeply influenced by their rich mythological tapestry, they named the planet in honor of Venus, their esteemed goddess of love, beauty, and fertility.

The brilliance of the planet in the sky served as a reflection of the goddess's divine beauty and allure. The dual appearances of the planet, visible both at dawn and dusk, further amplified its association with the goddess. This duality echoed Venus's two primary aspects in Roman lore: Venus Lucifera, symbolizing the morning star, and Venus Vespera, representing the evening star.

Moreover, Venus, in Roman mythology, wasn’t merely a deity of superficial charm; she held political significance too. Believed to be the mother of Aeneas, a hero whose descendants founded Rome, the planet's name became a celestial testament to the legacy and origins of Roman civilization.

Why Venus?

Its Brilliance

Venus, being the third brightest object in the sky after the sun and the moon, holds an undeniable allure. Its shining presence could easily be equated to the beauty and charm that the goddess Venus was known for in Roman mythology.

Dual Appearances

Venus appears both at dawn and dusk. This dual appearance might have been associated with Venus, the goddess's two main aspects: Venus Lucifera (the morning star) and Venus Vespera (the evening star).

Mythological Tales Surrounding Venus

In Roman mythology, Venus held significant importance. She was not only the goddess of love and beauty but was also believed to be the mother of the Roman people. Here are a few tales that further establish her significance:

Birth from the Sea: Venus is believed to have emerged from the sea foam, further enhancing her association with beauty as she was born from the pure and serene waters.

Mother of Aeneas: Legend has it that she was the mother of Aeneas, a Trojan hero. Aeneas's descendants, Romulus and Remus, are considered the founders of Rome, thereby linking Venus directly to the Roman civilization's origins.

In Conclusion

The naming of Venus provides an intriguing insight into the ways ancient civilizations made sense of the cosmos. They intertwined their observations of the night sky with their cultural beliefs, myths, and stories, adding depth and richness to our understanding of the universe. While the scientific study of Venus continues to reveal more about its atmosphere, geology, and potential for life, its historical and mythological context offers a captivating tale of humanity's quest to understand the universe.

The next time you gaze at the evening sky and spot Venus shimmering brilliantly, remember that you're not just looking at a planet. You're witnessing a celestial body laden with stories, myths, and historical significance that have inspired generations through the ages.

Why is Venus sometimes referred to as Earth's twin?

Venus and Earth are similar in size, mass, and composition, which is why it's often referred to as Earth's 'sister' or 'twin'.

Are there other cultures that have significant myths about Venus?

Yes. For instance, the Greeks called the planet Phosphorus and Hesperus for its morning and evening appearances, associating it with the god Aphrodite, their version of Venus.

Does Venus have any moons?

No, Venus does not have any natural satellites or moons.

How does Venus' atmosphere differ from Earth's?

Venus has a thick atmosphere primarily made of carbon dioxide, with clouds of sulfuric acid, making it extremely hot due to the greenhouse effect. This contrasts with Earth's nitrogen-oxygen atmosphere.

Why can't Venus support life as we know it?

The surface temperature of Venus can reach up to 900°F (475°C), hotter than a conventional oven. This extreme heat, combined with its toxic atmosphere, makes it inhospitable for life as we understand it.

How long is a day on Venus compared to Earth?

Surprisingly, a day on Venus (one rotation on its axis) is longer than its year (one orbit around the Sun). It takes about 243 Earth days for Venus to complete one rotation, but only about 225 Earth days to orbit the Sun.

Venus Planet Facts

Venus isn't as popular as other planets - but it still is interesting Named after the Roman goddess of love and beauty, Venus is deemed the sister planet due to the relatively similar size and bulk of the planet. Venus is one of the five planets visible to the human eye on the planet earth. Venus’s deep chromatic shadows cast a fluorescent yellow tone that can be seen prior to the sun rising and after the sun sets, therefore making it the brightest and most visible from earth.

Venus’s has a multitude of unique and odd characteristics ranging from topography, temperature, atmosphere, and rotation. Although Venus is considered relatively similar to the earth in size, it is completely opposite in its composition of land. 80% of the Venusian surface is coated by volcanic plains, and furthermore it has a very unique surface feature known as farra, which are flat volcanic like areas, also depicted as pancakes, that range from 20-50KM wide and up to 100km wide. However, the most interesting topographic feature of Venus is Maxwell, which is a 7 mile high and 540 mile long mount range! Venus’s weather is anything but punctual; its richly dense atmosphere ranges from a literally scorching 900 Fahrenheit all the way down to a freezing 50 Fahrenheit below. This is due to the immense amounts and more than any other planet within the solar system of CO2, and furthermore by the thermal inertia present. Venus has peculiar rotation relative to the earth, one that is documented as the slowest within our solar system, at an amazingly slow rate of once every 243 earth days.

One can see that although Venus and Earth are similar in some sense, the majority of their entities are unique and each to their own. The temperatures are drastically different, the surface is strange, and the temperature is literally unbearable. Overall, one can be assertively optimistic that humans don’t live on Venus.

The Rotation of Venus

Get ready for a fascinating journey into the mysterious dynamics of Venus's rotation. We are going to take a deep dive into the neighboring planet's fascinating and truly exceptional spinning behavior, so buckle up for the ride of your life. Forget everything you know about Earth's rotation, because Venus is about to take you somewhere completely new and different. Make sure your safety belts are buckled in because this space adventure will leave an indelible impression on your mind.

A Celestial Conundrum: Venus's Unusual Spin

Venus's retrograde rotation, which defies the general motion of most other heavenly bodies in our solar system, never fails to confound. When compared to Earth's graceful eastward revolution, Venus's bold embrace of the less travelled path by spinning from east to west stands out. Its daring defiance of convention is truly captivating.

Let us pretend for a moment that we have the technological capability (which, alas, we do not) to observe Venus from a higher vantage point in the cosmos. In this hypothetical scenario, we would find that it rotates clockwise on its axis, despite the fact that it actually spins to the east. This mysterious motion conjures up an image of Venus dancing an enigmatic, almost comical dance of its own making.

Time Dilation on Venus: Days and Years Entwined

Venus is a fascinating case study for people who feel like time is passing too quickly or too slowly. Ponder this: a single day on this planet outlasts an entire year! Yes, you heard that right. While Earth orbits the Sun over the course of roughly 365 days (marking the occasion of annual celebrations), Venus completes its solar circuit in approximately 225 Earth days. However, when it comes to completing a solitary axial rotation, the planet indulges in a leisurely rhythm spanning 243 Earth days.

Just picture yourself living on this scorching celestial sphere, where weekends last for the equivalent of almost half a year on Earth. But before you give in to the temptation of such prolonged leisure, keep in mind that it comes with sweltering temperatures and oppressive atmospheric pressures. Perhaps, in the grand scheme of things, there is something comforting about staying put on Earth.

Unveiling the Peculiar Rotation

Astronomers first noticed Venus's unusual spin after closely observing and analyzing the planet. Because of Venus's dense atmosphere and high atmospheric pressure, solving this mystery was no simple task. But in the pursuit of knowledge, scientists persevered and eventually cracked the code.

It was through the use of advanced telescopes and innovative techniques that the truth about Venus's rotation was unveiled. By carefully observing its surface features and following its motions over time, scientists were able to determine that this mysterious planet rotates in the opposite direction of Earth. It was a major breakthrough that has fascinated scientists and the general public alike with new theories and ideas.

The cataclysmic collision theory

According to one popular theory, Venus's peculiar rotation may have been caused by a massive cosmic collision. The idea is that billions of years ago, Venus was hit by a massive asteroid or maybe even another planet, causing a catastrophic event. This massive impact could have generated so much energy and force that it jarred Venus's rotational axis.

It is safe to assume that the aftermath of such an event would have been complete chaos. Intense upheaval and turbulence would have occurred all over the planet as a result of the gravitational forces at play. As the dust settled, Venus emerged from the cosmic wreckage with its new reverse rotation, forever marking its place in astronomical history.

The gravitational interplay hypothesis

Another intriguing theory suggests that Venus' rotation at first followed the standard cosmic flow but eventually gave in to the gravitational interplay with none other than our own Sun. Over countless cosmic epochs, this intricate dance between Venus and the Sun acted like a cosmic tug-of-war, gradually slowing down Venus's rotation and eventually reversing it.

To illustrate this, think of two celestial bodies, each with its own gravitational pull. As they orbit each other, their gravitational forces interact and influence each other's movements. For billions of years, Venus and the Sun have been engaged in this dance. Venus' rotation was slowly but steadily altered by the Sun's enormous gravitational pull. It is an intriguing theory that exemplifies the complex interplay between planets and the long-lasting effects their interactions can have on one another.

In Conclusion

Venus's rotation is a prime example of an anomaly in an otherwise well-documented universe. This scorching planetary realm, with its mysterious retrograde rotation and its temporal dance in which days eclipse years, never ceases to enchant us with its peculiarities. Venus's unique spin serves as a striking reminder that nature takes great joy in confounding expectations, whether the cause was a titanic collision or a gravitational ballet. Future research holds the potential to decipher the mysteries of this cosmic dance, revealing new elements of the incredible cosmic story being written above our heads.

What's the rotation period of Venus?

Venus has an incredibly slow rotation period compared to other planets in our solar system. It takes approximately 243 Earth days for Venus to complete one full rotation on its axis.

What type of rotation does Venus have?

Venus has what is known as a retrograde rotation. This means that it rotates on its axis in the opposite direction of its orbit around the Sun. While most planets in our solar system rotate counterclockwise, Venus defiantly spins clockwise.

Why does Venus rotate so slowly?

Venus's rotation has slowed over billions of years due to gravitational tidal forces from the Sun. Friction caused by Venus's thick atmosphere also slowed the planet's rotation.

Could Venus change rotation directions again?

With enough time and the right combination of tidal forces and atmospheric friction, Venus could flip its rotation again in the distant future.

Soviet Rocket to Venus

During the Cold War, the United States and the Soviet Union competed in every field, including weapons, science and technology. Another huge part of the rivalry consisted of space and space travel. The space race of the 1960s was nothing short of epic; the U.S. and Soviet Union could compete over a plethora of first, such as first person in space, first person to walk on the moon, etc. A less glamorized, but equally important, goal was to reach and land on the planet Venus. Venus, though very close to Earth and similar in size is not nearly as welcoming as our home planet. With a carbon dense atmosphere, temperatures and pressure on the planet are treacherous. The Soviet Union would spend millions of dollars, embarking on several missions that attempted to land on the harsh, hot Venus surface. These projects would be named after the Russian name for Venus, Venera and would begin with the unsuccessful first mission of the Venera 1.

In 1961, the Soviet Union made its first attempts to conquer Venus with the Venera 1 space probe. On February 12, 1961 the Venera 1 launched with a relatively simply mission: do a flyby of Venus. The probe was the first of its kind and its model was considered the standard for the modern planetary probe from that point forward. The probe had a wide variety of new capabilities and features. Venera one was fitted with sensors to measure solar wind and cosmic radiation. It also boasted of being the first probe to be launched from orbit with a four stage engine. The Venera was also one of the first probes to be spin stabilized and have the capability to perform mid-course corrections. The early stages of the probe’s journey were very successful, but shortly after being the first vessel to confirm the presence of solar wind throughout deep space, the Venera 1 lost contact with its Soviet handlers on February 27. Venera 1 passed within 100,000 km of Venus, before entering an orbit around the sun, where it remains today, still sending out weak signals.

The launch of Venera 1 was a very important point in the history of Venus’s exploration. Although the probe was unsuccessful at its initial mission, it was a very successful piece of technology that implemented a variety of new design improvements. The Venera 1 would be followed by more than a dozen other Venera probes in the decades to come. Although under heavy competition from NASA’s Pioneer 5 and Mariner programs, the Soviet Union would eventually beat out the competition and reach their goal of entering the atmosphere in 1967, as well as landing on the surface in 1970. The Venera project would go on to yield a variety of other firsts, which were pivotal points of pride during the Cold War space race. Venera probes would be the first to enter the atmosphere of another planet, first to land on another planet, as well as being the first to provide color photographs of Venus’s surface.

Temperature on Venus: A Searing Mystery

Venus, our neighbouring planet, has long fascinated astronomers and casual sky-gazers alike. Often dubbed the 'sister planet' to Earth due to its similar size, the conditions on Venus are, however, far from sisterly. One of the most intriguing aspects of Venus is its extreme temperature. But why is Venus so hot? Let's dive into the scorching topic of Venusian temperatures.

How Hot is Venus?

For starters, Venus is the hottest planet in our solar system, even hotter than Mercury, which is closer to the Sun. Average temperatures on Venus hover around 465°C (869°F). To put this into perspective:

It's hotter than a home oven set to its maximum temperature. It's more than hot enough to melt lead.

Volcanic History: The Fiery Past of Venus

One cannot delve into the temperature and atmospheric composition of Venus without touching upon its volcanic history. The planet's surface tells a story of intense volcanic activity that once ruled and, to an extent, sculpted its present landscape.

A Volcanic Playground

A glance at Venus's topography reveals:

  • Coronae: Circular structures that are believed to have formed due to the upwelling of magma from the planet's interior.
  • Pancake Domes: These are broad, flat volcanic structures, some of which span tens of kilometers across, indicating substantial lava flows.

A Hand in the Greenhouse?

While it's clear that volcanic eruptions released vast amounts of CO2 into the atmosphere:

  • The majority of Venus's atmosphere is made up of carbon dioxide, which is a common volcanic emission.
  • These volcanic activities could have contributed to the existing CO2 levels, thus accentuating the greenhouse effect.
  • Recent Activity

    While most of Venus's volcanic landscape appears ancient:

    Some researchers suggest that Venus may still be geologically active. There have been hints of recent lava flows, suggesting that some volcanoes might have erupted in the not-so-distant past.

    These potential recent eruptions could play a role in maintaining the planet's thick CO2-dominated atmosphere.

    Contrast with Earth

    On Earth, carbon dioxide emitted by volcanoes often becomes trapped in carbonates like limestone, mitigated by water and plate tectonics. Venus, with its lack of significant water and plate tectonics, doesn’t have the same luxury. The CO2 remains in the atmosphere, adding to its temperature-enhancing blanket.

    Venus's volcanoes, both ancient and potentially recent, have played a definitive role in the planet's climatic tale. From the scorching plains dominated by pancake domes to the mysterious coronae structures, these volcanic features not only give Venus its unique geographic fingerprint but also offer insights into its temperature history. When we think of the hottest planet in our solar system, it's essential to remember that its fiery image isn't just metaphorical – it's deeply rooted in its volcanic past.

    The Greenhouse Effect: On Steroids

    The Main Culprit: The predominant reason for Venus's extreme heat is the greenhouse effect. Let's break this down:

    • Greenhouse gases: Just like on Earth, certain gases in a planet's atmosphere can trap heat. Carbon dioxide (CO2) is a major one.
    • Venus’s atmosphere: It's made up of about 96.5% CO2. With such a high concentration, the greenhouse effect runs rampant, trapping heat effectively.

    A Day Longer Than a Year?

    Surprisingly, the rotation of Venus plays a part in its high temperatures. Here's why:

    • Slow Rotation: A day on Venus (one full rotation) takes about 243 Earth days. It’s even longer than a year on Venus (the time it takes to orbit the Sun), which is about 225 Earth days.
    • Prolonged Daylight: This slow spin means that its surface gets exposed to the Sun's heat for extended periods, allowing for more heat absorption.

    Thick Atmosphere, More Pressure

    Another contributing factor is the thickness of Venus's atmosphere. It's about 90 times denser than Earth's atmosphere. This creates a high-pressure environment, further amplifying the temperatures.

    No Water, No Relief

    Water is a great regulator of temperature, but Venus lacks significant water sources.

    • Absence of Oceans: Earth's oceans play a crucial role in moderating our planet’s temperature. Venus has no such luxury.
    • Water Vapor: The little water vapor that does exist in Venus’s atmosphere is another greenhouse gas, adding to the heating effect.

    Reflectivity Isn't Enough

    Despite its high temperatures, Venus is very reflective due to the presence of thick clouds made primarily of sulfuric acid.

    Albedo: This measure of reflectivity is about 0.7 for Venus, meaning it reflects 70% of the sunlight that falls on it.

    However, the sunlight that penetrates these clouds gets trapped by the greenhouse gases, again boosting temperatures.

    Lessons for Earth

    Venus serves as a poignant lesson about the potential consequences of runaway greenhouse effects. With ongoing concerns about climate change and global warming:

    Observing Venus makes it clear just how powerful greenhouse gases can be in dictating a planet's temperature.

    Efforts to reduce CO2 emissions and other greenhouse gases on Earth gain more significance when we consider the Venusian example.

    Conclusion: Venus – A Hotbed of Climate Extremes

    As we've seen, a combination of a thick CO2-rich atmosphere, slow rotation, absence of oceans, and a dense atmospheric pressure makes Venus the scorching hot world that it is. While the temperatures make the idea of human exploration challenging, the lessons we glean about atmospheric science and the power of the greenhouse effect are invaluable. As we continue to study Venus, we're not just exploring another world; we're gaining insights into the delicate balance of planetary climates and the role we play in our own planet's future.

    Why is Venus hotter than Mercury, even though Mercury is closer to the Sun?

    While Mercury is closer to the Sun, Venus's thick atmosphere, rich in greenhouse gases, traps heat far more effectively. This runaway greenhouse effect results in Venus having a higher average temperature than Mercury.

    Could the volcanic activity on Venus ever make it suitable for human colonization?

    While volcanic activity has significantly shaped Venus's landscape, the planet's extreme temperatures and high atmospheric pressures, combined with its corrosive atmosphere, make it a very challenging environment for human colonization. Any future colonization efforts would require significant technological advancements and protective measures.

    How does the greenhouse effect on Venus compare to that on Earth?

    Venus offers an extreme example of the greenhouse effect. Its atmosphere is around 96.5% carbon dioxide, compared to Earth's 0.04%. As a result, Venus experiences a far more potent greenhouse effect, leading to its scorching temperatures. While Earth's greenhouse effect is milder, the study of Venus offers cautionary insights into the consequences of unchecked greenhouse gas accumulation.

    Are there still active volcanoes on Venus?

    There is evidence to suggest that Venus might still be geologically active. Some observations indicate possible recent lava flows, hinting at volcanic eruptions in the not-so-distant past. However, definitive proof of current volcanic activity remains elusive.

    How does Venus's lack of water impact its temperature and volcanic activity?

    Water plays a critical role in temperature regulation. On Earth, oceans absorb and distribute heat, moderating global temperatures. Venus's lack of significant water sources means it doesn’t benefit from this temperature regulation. Additionally, on Earth, carbon dioxide emitted by volcanoes can become trapped in carbonates, a process facilitated by water. In contrast, on Venus, the CO2 remains in the atmosphere, enhancing the greenhouse effect.

    Moons of Venus

    Venus is moonless. Venus being the second closest planet to the sun has been deemed the only planet without moons besides Mercury. It is hard to state whether or not Venus has had any moons in the past, but as to why there are no moons on Venus is a complete mystery. There is a belief that Venus alongside with Mercury does not have moons due to the fact that both planets are relatively closer than the other six planets to the sun, and that if both planets did have moons that they would be greatly affected by the gravitational pull of the sun.

    Another theory about Venus and its lack of moons is that Venus is the only planet to actually rotate backwards and even more interesting is that one day on Venus is actually longer than one year. These interesting and strange characteristics point to many different theories and conspiracies. The fact that this planet spins backwards is possible proof that the planet has once had a major collision, which is a theory that earth shares as well. Therefore, it is possible that this collision had actually material floating around that coalesced into a possible moon or even moons. However, a belief that the suns gravitational pull had actually made the moon collapse back into the planet.

    Evidence is strong and conspiracies align with the notion that Venus had once had moons, possibly 300-500 million years ago. However, as of today, there are no moons that surround Venus.
