Evershed (crater)
Encyclopedia
Evershed is a lunar
impact crater
on the far side of the Moon
, named after the English solar astronomer John Evershed
. It is located to the northeast of the larger crater Cockcroft
, and to the north of the smaller Van den Bergh
.
This crater has a worn outer rim that is somewhat indented and narrower along the eastern side where the formation overlays an older crater. The satellite crater Evershed R is attached to the outer southwest rim. There are small craters along the southern and southeast rim
. The interior floor contains an irregular ridge near the mid-point and some rugged terrain in the south, with various tiny craterlets marking the remaining relatively level surface.
Moon
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...

Rim (craters)
The rim of a crater is the part that extends above the height of the local surface, usually in a circular or elliptical pattern. In a more specific sense, the rim may refer to the circular or elliptical edge that represents the uppermost tip of this raised portion...
