List Of Stars In The Sky

Small but flaming balls of luminous plasma, stars are everywhere! Stars are extremely common in some geographic locations as to others they may rarely be seen. The numbers of stars is considered by some infinite as there is no solid substantial actual number of stars within the universe that scientists can conclude today. However, there are a few stars that are more common and visible than others. These select few have common names that are agreed upon by scientists around the world. Here is a list of some of the stars that are more common:

  • 1. Sirius
    It is the brightest star in the night sky, with a magnitude of 1.46. Its name came from the Ancient Greek, Seirios, which means glowing or scorcher. What you see in the sky, the single bright star, is actually a binary star system, which is a white main sequence star of spectral type A1V, mostly known as Sirius A, and a faint white dwarf DA2, known as Sirius B. Normally, the distance between Sirius A from its companion ranges from 8.1 to 31.5 AU. The reason why Sirius is so bright is because of both intrinsic luminosity and the proximity to Earth. In other words, Sirius is one of Earth’s near neighbors with distance of 2.6 parsecs. Sirius A is about 25 times more luminous and about twice as massive as the Sun. However, it has a very low luminosity compared to other bright stars such as Canopus or Rigel. It is about 300 million years old and mainly consists of bright bluish stars. Sirius B is more massive than Sirius A and it was a red giant before it became a white dwarf about 120 million years ago.

  • 2. Canopus
    It is the brightest star in the Southern constellation of Carina and Argo Navis, and a bright giant of spectral type F. Moreover, it is also the second brightest visual star in nights, after Sirius. Its visual magnitude is about -0.72 and an absolute magnitude is about -5.53. When seen with the naked eye, it is essentially white. Canopus is located in the far southern sky with declination of of -52° 42' (2000) and a right ascension of 06h24.0m.

  • 3. Arcturus
    This star is the brightest star in the constellation Boφtes. In addition, it is also the brightest star in the northern hemisphere and the fourth brightest star in the night side with a magitiude of -.04. It has a very distinct color of orange-yellow that can be seen with the naked eye. It is one of the few stars easily found in both the northern and southern hemisphere, being only 20 degrees from the celestial equator.

  • 4. Alpha Centauri A
    It is the brightest star in the southern constellation of Centaurus. It has 159% of the luminosity of our Sun. Using declination, one can find this star at -60° 50' 13.761? and using right ascension the star is located at 14h39m36.4951s. Alpha Centauri A is actually one half of the binary star system Alpha Centauri AB.

  • 5. Vega
    Vega is the brightest star in the constellation Lyra, as well as the fifth brightest star in all of the night sky. Vega is one of the more interesting stars to astronomers and was the northern pole star multiple times in recorded history. Many argue that it is the second most important star after the Sun.

  • 6. Rigel
    It is the brightest star in the constellation Orion with a visual magnitude 0.18. The right ascension of Rigel is 05h14m32.272s and the declination is -08° 12' 05.91?. The star was named after the fact that is the left foot of Orion.

  • 7. Spica
    This blue giant is the brightest star in the constellation Virgo and the 15th brightest star in the night sky. The star is a noteworthy distance away from Earth, 260 light years. The right ascension of Spica is 13h25m11.5793s and the declination is -11° 09' 40.759?. Spica is known for being the nearest massive binary star system to the sun and is therefore a star often studied by astronomers.

  • 8. Antares
    Antares is a red supergiant known for being the 16th brightest star in the night sky. It is a very large star with a radius 800 times that of the Sun and is 10,000 times more luminous. Its right ascension is 16h29m24s and its declination is -26° 25' 55?.

  • 9. Pollux
    The yellow-orange giant Pollux, is the brightest star in the constellation Gemini. It is reported to have a planet orbiting around it, one of the only stars to have this visible with the naked eye. Its right ascension is 07h45m19.4s and its declination is +28° 01' 35?.

  • 10. Fomalhaut
    It is the brightest star in the constellation Piscis Austrinus and is generally accepted to be one of the brightest stars in the entire sky. It can be seen low in the southern sky in fall and early winter for the northern hemisphere. Its right ascension is 22h57m39.0465s and its declination is -29° 37' 20.050?.

  • 11. Deneb
    It is the brightest star in the constellation Cyngus. Deneb is one of the vertices in the Summer Triangle, a well-known astronomical asterism. Deneb is a blue-white supergiant and is known for being one of the most luminous stars near our planet. Its right ascension is 20h41m25.9s and its declination is +45° 16' 49?.

  • 12. Aldebaran
    Aldebaran is another star that can boast of being one of the brightest stars in the sky. It is an orange giant located in the Taurus constellation with a magnitude of 0.87. It is one of the easiest stars to find in the sky, being on the brightest star on line with Orion’s belt. Its right ascension is 04h35m55.239s and a declination of +16° 30' 33.49?.
