Quizplus · Accepted Answer

The gravitational pull of the Moon is weaker than that of the Earth, so the minimum speed required to maintain an orbit around the Moon is less than the minimum speed required to maintain an orbit around the Earth. Therefore, the answer is less than 8 km/s.

Minimal Orbital Speed About Earth Is About 8 Km/s, and About
