Moon turned constantly to the earth by the same side? The answer is simple: the speed of rotation of the moon around the Earth is absolutely identical to the speed with which he makes a revolution around its axis of rotation is the Moon around the Earth and around its own axis synchronized.

The reverse side of the moon - part of the lunar surface, which is not visible from Earth.

Period of the Moon around the Earth is equal to the period of rotation around its axis, so he turned to the Earth is always one side. Morey, in contrast to the visible side, almost none. Sometimes it is erroneously called the dark side of the moon, but it is not - the sun illuminated this aspect at least visible.

Interestingly, the Earth can see more than half of the lunar surface. Because the orbit of the moon around the earth elliptical, not circular, its orbital motion speed varies depending on how close it is to the planet. The speed of rotation of the Moon around its axis it remains constant. When the moon is schonaydali from Earth, its orbital speed is low, and this is enough to rotation speed has become greater. This gives the opportunity observers from the ground a little "spy" and see the opposite half. The effect of the moon is called libration and allows you to see up to 59% of the Moon from Earth.
