* Tidal Locking: The Moon is tidally locked to Earth. This means that the time it takes the Moon to rotate once on its axis (its rotational period) is exactly the same as the time it takes to orbit the Earth (its orbital period).
* Synchronous Rotation: This results in the same side of the Moon always facing Earth.
* Why This Happens: Gravity pulls on the Moon, creating a slight bulge on the side facing Earth. Over time, this bulge has slowed the Moon's rotation until it matches its orbital period.
So, while it's not technically "full rotation," the Moon's rotational and orbital periods being the same is the reason we only see one side.
