### 1 Kepler’s Third Law - University of Massachusetts Amherst

people.astro.umass.edu

Kepler’s Third Law says P2 = a3: After applying Newtons Laws of Motion and Newtons Law of Gravity we nd that Kepler’s Third Law takes a more general form: P2 = " 4ˇ2 G(m1 +m2) # a3 in MKS units where m1 and m2 are the masses of the two bodies. Let’s assume that one body, m1 say, is always much larger than the other one. Then m1 ...
