~	Most of the Moon's surface is covered with regolith, a mixture of fine dust and rocky debris produced by meteor impacts.
~	The Moon has no atmosphere. But evidence from the Clementine spacecraft suggests that there may be water ice in some deep craters near the Moon's south pole.
~	Most rocks on the surface of the Moon seem to be between 4.6 and 3 billion years old.
~	The gravitational forces between the Earth and the Moon cause some interesting effects. The most obvious is our ocean tides.
