Mercury has a radius of 2440 km. A satellite is in circular orbit around Mercury. It travels at a distance of 124 km above the surface and its period of rotation is 1 hour 31.5 minutes.
a) Estimate the Mass of Mercury. State which formula(s) you applied and why.
b) Estimate Mercury's mean density. You can assume a spherical planet.
c) Compare your answer to the mean density of Earth. Why is it larger/smaller?

A satellite is in circular orbit around an unknown planet. A second, different, satellite also travels in a circular orbit around this same planet, but with an orbital radius four times larger than the first satellite. Sue-Bob, the bad physics student, says: "The gravitational force of the planet depends inversely on the orbital radius squared. Since the second satellite's orbitai radius is four times that of the first satellite, the second satellite experiences on-sixteenth the gravitational force that is exerted...
