The moon's Prometheus and Pandora orbit Saturn at 139,350 and 141,700kilometers.  1) Use Newton's version of Kepler's third law to find the orbital periods of the two moons. 2) Find the percent difference in their distances and their orbital periods 3) Consider the two moons in a race around Saturn: In one Prometheus orbit, how far behind is Pandora (in units of time)? In how many Prometheus orbits will Pandora have fallen behind by one of its own orbital periods? Convert this number of periods back into units of time. This results in how often the satellites pass by eachother.
