WebKepler’s Third Law. The ratio of the periods squared of any two planets around the sun is equal to the ratio of their average distances from the sun cubed. In equation form, this is. T 1 2 T 2 2 = r 1 3 r 2 3, where T is the period (time for one orbit) and r is the average distance (also called orbital radius). WebLater analysis by Kepler showed that these orbits are actually ellipses, but the orbits of most planets in the solar system are nearly circular.
