... The square of a planet's period, T, is directly proportional to the cube of its average distance from the Sun, r. Mathematically this can be expressed as: R3 / T2 = k The implication of Kepler's Third Law is that planets more distant from the Sun take longer to orbit the Sun. Kepler's laws of planet ...
