Planets Known Before the Telescope

Before the telescope - it was very tough to know what was out there.

The invention of the telescope could possibly be the hallmark invention of the century, as it provided a means of discovering things in the solar system that were to distant to the naked eye. The telescope being invented in the 17th century, by Greek Mathematician Giovanni Demisani, was first shown in Galileo�s banquet. From then on the infatuation of the telescope only grew to exponential levels. However, prior to the telescope, how did individuals see other planets? Unfortunately, the only way was with the naked eye. With the naked eye however, an individual at the correct time of day could see Mercury, Venus, Mars, Jupiter, Saturn, and most obviously the earth.

These six planets are visible to the naked eye because of various reasons. The earth should have a concrete and stand alone answer for itself as to why it can be seen, however as for planets like Jupiter and Saturn, if looking at the correct time of day, you can see these planets somewhat clearly due to their enormous size. The best time to see these planets is before the sunrise or right after the sunset. Mars, Mercury, and Venus are relatively closer than Jupiter or Saturn and therefore if presented at the correct time of day and conditions are visible as well.

Prior to the telescope there were many theories and falsely acclaimed planets that were truly stars, moons, or other particles in the sky. The truth of the matter is that only six planets are visible to the human eye, while Uranus and Neptune can only be seen with a telescopic device.
