has definition Natural satellite of Earth. Studies of lunar rocks have shown that melting and separation must have begun at least 4.5 × 109 years ago,so the crust of the Moon was beginning to form a very short time after the solar system itself. It would have taken only 107 years to slow the Moon's rotation into its present lock with its orbital period. The Moon's orbit is always concave toward the Sun.has source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press, 2001-09-27 09:31:57.0
