Brahe’s assistant‚ Kepler was given the task of studying and attempting to understand the orbit for planet Mars. The orbit of Mars was particularly difficult because Copernicus had correctly placed the Sun at the center of the Solar System‚ but had erred in his assumption of circular planetary orbits. After numerous experiments and mathematical calculations‚ he finally realized the obits of the planets were in fact not circular as Aristotle had previously insisted and Copernicus assumed correct‚ but

belief was that the sun exerted a force on the planets orbiting it. In 1596‚ at the age of 25‚ he published a book called Mystery of the Cosmos. His book logically explained why the sun lies at the center of the solar system. He noticed that Mercury and Venus always seem to be close to the sun‚ unlike Mars‚ Jupiter and Saturn. This is because Mercury and Venus orbits are closer to the sun than Earth’s. Kepler said that if the sun and all the planets orbited Earth‚ there is no explanation as to why

Introduction It is easy to flip to the index of an astronomy textbook to discover that‚ say‚ the Sun lies 150 million kilometers away from Earth. It is far more difficult (if not impossible)‚ however‚ to picture this distance in the human mind. In this exercise‚ we will learn to access the often unpalatable distances encountered in astronomy

answer for this question. Scientists have found many planets which have the potential to support life. However‚ it is the Earth’s neighbor‚ Mars‚ which has the biggest chance that life may exist on.
