The Moon is Earth's only known natural satellite,There are a number of near-Earth asteroids including 3753 Cruithne that are co-orbital with Earth: their orbits bring them close to Earth for periods of time but then alter in the long term . These are quasi-satellites and not true moons. For more...

Mare Imbrium
Mare Imbrium, Latin for "Sea of Showers" or "Sea of Rains", is a vast lunar mare filling a basin on Earth's Moon and one of the larger craters in the Solar System. Mare Imbrium was created when lava flooded the giant crater formed when a very large object hit the Moon long ago...

impact basin. About one crater-diameter to the southeast is the Catena Leuschner crater chain, while further to the south is Catena Michelson.

The rim of this crater is marked in several locations by smaller impacts that lie along or across the side. Only the west-northwestern part is relatively free from impacts. The northeastern rim is somewhat indented into the interior of the crater. Within the interior the floor is relatively featureless and level, with only a few tiny craterlets to mark the surface.
