In fact, as the Moon travels around the Earth in a counter-clockwise orbit every 27.5 days, it also completes one full rotation on its axis â also moving in a counter-clockwise direction.
The Moon does rotate around its own axis, actually, but it always rotates at just the right speed so that it's facing the earth; this is because of the Earth's gravity, pulling the moon slightly toward it. The Moon used to rotate on its own axis, but one side is more massive than the other.
