Kepler's Third Law of planetary motion states that the further a planet is from the Sun, the slower it moves in its orbit. This is because of the inverse relationship between the distance of the planet from the Sun and the period of its orbit - the farther a planet is from the Sun, the longer it takes to complete one orbit.
