Question

Quizplus · Accepted Answer

The Moon's rotational and orbital periods are equal, meaning that it takes the same amount of time for the Moon to rotate on its axis as it does for it to complete one orbit around Earth. The Moon's orbital and rotational periods are equal, which is why we always see the same side of the Moon from Earth.
