The view of the Moon from the Earth

You may have noticed that although the Moon is spinning on its axis you always see the same side of the Moon when you look at it from the Earth.

This is because the Moon takes the same time to spin once on its axis as it does to make one complete orbit of the Earth (27.3 days).

N.B The size of the Moon has been exaggerated and its distance form the Earth made smaller to make the animation easier to see.
