Whenever two Apollo astronauts were on the surface of the Moon, a third astronaut orbited the Moon. Assume the orbit to be circular and 160 km above the surface of the Moon, where the acceleration due to gravity is 1.42 m/s2. The radius of the Moon is 1.70 Times 106 m.Explanation / Answer
g = G*M/(R+h)^2
1.42 = 6.67*10^-11*7.35
