Once in a Blue Moon...

The Moon has fascinated mankind throughout the ages. It is the only natural satellite of Earth: Called Luna by the Romans, Selene and Artemis by the Greeks, and many other names in other mythologies. Due to its size and composition, the Moon is sometimes classified as a terrestrial "planet" along with Mercury, Venus, Earth and Mars. The Moon is spherical in shape, is not self-luminous, but rather reflects the light of the distant Sun and circles the Earth once per month. It has no atmosphere, the sky always appears dark, even on the bright side.

The Moon always shows us the same face everyday and this is why the features on the moon never change. Since both the Earth and Moon are rotating and orbiting, how can this be possible? Long ago, the Earth's gravitational effects slowed the Moon's rotation about its axis. Once the Moon's rotation slowed enough to match its orbital period (the time it takes the Moon to go around Earth) the effect stabilized. People often refer to "the dark side of the moon", but there is no such thing. The sun shines on all sides of it in turn. However, there is a "far side of the moon" which is never seen from the earth.
