Mees is a crater

Impact crater

In the broadest sense, the term impact crater can be applied to any depression, natural or manmade, resulting from the high velocity impact of a projectile with a larger body...

 on the far side of the Moon

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...

. It is located in a part of the lunar surface that is sometimes brought into view of the Earth

Earth

Earth is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System's four terrestrial planets...

 under conditions of favorable libration

Libration

In astronomy, libration is an oscillating motion of orbiting bodies relative to each other, notably including the motion of the Moon relative to Earth, or of Trojan asteroids relative to planets.-Lunar libration:...

 and illumination. Even at such a time, however, this feature is seen from a very low angle and little detail can be perceived.

This crater lies in the northern edge of the huge skirt of ejecta that surrounds the Mare Orientale

Mare Orientale

Mare Orientale is one of the most striking large scale lunar features, resembling a target ring bull's-eye. Located on the extreme western edge of the lunar nearside, this impact basin is difficult to see from an Earthbound perspective.Material from this basin was not sampled by the Apollo program...

 impact basin. This feature lies several hundred kilometers to the south of Mees, where the outer mountain range Montes Cordillera

Montes Cordillera

Montes Cordillera is a mountain range on the Moon. This feature forms the outer wall of peaks that surround the Mare Orientale impact basin, the inner ring being formed by the Montes Rook...

 is located. To the southwest of Mees is the crater Elvey

Elvey (crater)

Elvey is a lunar crater that is located on the far side of the Moon. It is located near the northern edge of the blanket of ejecta that surrounds the Mare Orientale impact basin. To the north of Elvey is the smaller crater Nobel....

 and to the northeast is Einstein

Einstein (crater)

Einstein is a large lunar crater that lies along the western limb of the Moon, making it difficult to observe from the Earth. The visibility of this formation is affected by libration effects, but even under the best conditions not much detail can be observed except from lunar orbit...

, both about three crater diameters distant.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Mees.
