Kepler's laws of planetary motion

In astronomy, Kepler's laws of planetary motion are three scientific laws describing the motion of planets around the Sun. 1. * The orbit of a planet is an ellipse with the Sun at one of the two foci. 2. * A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. 3. * The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit. Kepler's laws are part of the foundation of modern astronomy and physics.
