Johannes Kepler studied motion of planets and made tree laws regarding planetary motion.
Explanation:
THe third law states that "The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit. This captures the relationship between the distance of planets from the Sun, and their orbital periods.".
in simple terms closer orbits will have higher speeds.
