Question

Quizplus · Accepted Answer

The time it takes for a satellite to orbit Earth is determined by the distance between the satellite and the center of Earth. The Moon is about 60 times farther away from Earth than a satellite in low Earth orbit, so it would take much longer for the Moon to orbit Earth. The Moon takes about 28 days (or one lunar month) to orbit Earth once.
