Kepler's laws of planetary motion, in astronomy and classical physics, laws describing the motions of the planets in the solar system. read more
In astronomy, Kepler's laws of planetary motion are three scientific laws describing the motion of planets around the Sun. Figure 1: Illustration of Kepler's three laws with two planetary orbits. (1) The orbits are ellipses, with focal points F 1 and F 2 for the first planet and F 1 and F 3 for the second planet. read more
