Bottom line: A slight north-south rocking and east-west wobbling of the moon – known as lunar libration – let's us see as much as 59% of the moon's surface. That's true even though one side of the moon always faces Earth.

Explanation:
one side
Only one side of the Moon is visible from Earth because the Moon rotates on its axis at the same rate that the Moon orbits the Earth—a situation known as synchronous rotation, or tidal locking. The Moon is directly illuminated by the Sun, and the cyclically varying viewing conditions cause the lunar phases.
