Laws of motion Law 1: The orbit of every planet is an ellipse sun at focus.
Law 2: A line joining a planet and the sun sweeps out equal areas during equal intervals of time.
Law 3: The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit.
