    He is best known for his eponymous laws of planetary motion. His laws were...
    1. The orbit of every planet is an ellipse with the Sun at one of the two foci.
    2. A line 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 directly proportional to the cube of the semi-major axis of its orbit.
