The moon rotates around it's own axis while it orbits planet earth.
The moon's rotation is "in synch" with the orbit around earth (1 rotation during 1 orbit).
That is why we see only one side of the moon from earth.
It is interesting to note that although the moon orbits planet earth , planet earth also wobbles around their common path (called "barycenter") around the sun.
