Lunar Libration

We always see the same side of the moon because it takes the same time to rotate on itself as it does to go around the earth.
But although we always see the same face, we do not see exactly 50% of its surface, but 59%.
This is because when the moon is closer to the earth it speeds up, and when it is farther away it slows down, but it keeps the speed of rotation constant on itself.
This causes that from the Earth we perceive small oscillations in the face that it shows us, which is known as Lunar Libration.
