## Homework Statement

A satellite is in a circular orbit very close to the surface of a spherical planet. The period of the orbit is T = 2.52 hours.

What is density (mass/volume) of the planet? Assume that the planet has a uniform density.

Hint: "very close to the surface" means that Rorbit = Rplanet
