the period of rotation of the moon is about 27 days, 8 hours. The mass of the moon is 7.35x10^22 kg, and the radius of the moon is 1.74x10^6 m. I wish to place a synchronous (period of orbit = period of the moons rotation) satellite in orbit about the moon.
A) Find the radius of the satellites orbit.
B) Find the height of the satellite above the moons surface.
