Kepler’s laws Kepler provided three laws for planetary motion, based on Brahe’s observations. 1. The orbit of a planet is an ellipse with the Sun located at one focus 2. The radius vector drawn from the Sun to a planet sweeps out equal areas in equal time 3. Planetary periods of revolution are proportional to mean distance to the Sun ^3/2
