Does the Moon rotate?

Yes.The Moon rotates at the same rate that it revolves around Earth, about once every 27 days. Because one spin matches one orbit, the same side of the Moon always faces us. This is called synchronous rotation.

What's actually true

The Moon spins, exactly once per orbit. Because we always see the same face of the Moon, it's easy to think it doesn't spin at all. It does: the Moon rotates at the same rate that it goes around Earth, about once every 27 days. Turning once per lap keeps the same side facing us, like a person walking around a table while always facing its center. This is called synchronous rotation.

Takeaway: The Moon does rotate, once every orbit of about 27 days. That's exactly why we always see the same side.

Why people believe it

The evidence seems to point the other way. The Moon's face never changes, so it looks like it isn't turning. But think about what would happen if it really didn't spin: as it went around Earth we'd see every side of it in turn. Keeping one face toward us actually requires exactly one turn per lap, which feels backwards at first.
