determine the mass of Jupiter using data from its moon Sinope: period of orbit is 2.075 years, average orbital distance is 0.158 astronomical units.

If the mass of the second object is very small compared with the first mass, then, to a good approximation, P2 = a3 / M1. Solving for the mass, we get M1 = a3 / p2 . Use this mass formula to... more
