Kepler-Original+Theories

Original Theories

 * Before Johannes Kepler, people did not know how to explain planetary motion
 * There was no way to calculate the orbit of planets because people believed that all planets orbit in a circular motion
 * Nicolaus Copernicus came up with the theory of the planets in our solar system revolving around the sun instead of the earth
 * Johannes Kepler was one of the few scientists to believe Copernicus and proved his theory correct with three natural laws on planetary motion
