Discover the cosmos! ... September 13, 1997 . Kepler Discovers How Planets Move . ... Explanation: Johannes Kepler used simple mathematics to describe how planets move. ... Kepler was able to use Brahe 's data to show that planets move in ellipses around the Sun ( Kepler's First Law ), that planets move proportionally faster in their orbits when they are nearer the Sun ( Kepler's Second Law ), and that more distant planets take proportionally longer to orbit the Sun ( Kepler's Third Law ). ...

Thanks to numerous ground and space-based surveys, we are now aware of over 1800 planets orbiting other stars, with another nearly 5000 candidates from the Kepler Mission awaiting confirmation. ... The answer to this question lies in the study of young planets and their formation environments. In this talk I will show how high-precision time series data from space telescopes is beginning to illuminate the conditions surrounding planet formation and the star-disk connection. ...

In ancient times the solar system was thought to be the whole Universe, so the study of planetary motions was cosmology. ... The planets other than the Moon and Sun generally move West to East through the stars, but occasionally stop and move in the opposite direction ( retrograde motion). In order to explain the retrograde motion of the planets, the geocentric model of the Solar System shown above puts the planets on small circles called epicycles . ...
