Kepler's Third Law

Demonstration showing how the 3rd law works for 2 different objects orbiting the Sun. The range of possible orbits is 2 A.U. to 15 A.U., with these numbers randomly generated.

You can determine the sizes of the orbits by using the special form of Kepler's Third Law, P2=a3, and using the periods that are output. Your values can then be checked by entering them in the boxes on the left.
