How Long Does It Take the Moon to Rotate on Its Axis?

Due to the fact that the moon's rotational period and orbital period are both about 28 days, it deceivingly appears that the moon never rotates. This is the result of the Earth's gravity creating "tidal bulges" on the moon which maintain this slow rotation. Most other moons in the solar system are subject to the same tidal forces and, thus, always show the same face to the planet below.
