Mösting is a small lunar

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...

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...

Mare Insularum

Mare Insularum is a lunar mare located in the Insularum basin just south of Mare Imbrium. The basin material is of the Lower Imbrian epoch, with the mare material of the Upper Imbrian epoch. The mare is bordered by the craters Copernicus on the east, and Kepler on the west...

Sömmering is the lava-flooded remains of a lunar crater on the eastern edge of the Mare Insularum. To the southeast is the crater Mösting, and north of Sömmering lies a similar flooded crater designated Schröter...

Flammarion (lunar crater)

Flammarion is a lunar crater on the south edge of Sinus Medii. It is located between the crater Mösting to the northwest and Herschel to the southeast. The bowl-shaped Mösting A intersects the western rim of Flammarion....

. Mösting has a terraced inner wall and a small central hill at the mid-point of the floor.

To the south-southeast lies the bowl-shaped Mösting A. This small feature formed the fundamental location in the selenographical coordinate

Selenographic coordinates

Selenographic coordinates are used to refer to locations on the surface of Earth's moon. Any position on the lunar surface can be referenced by specifying two numerical values, which are comparable to the latitude and longitude of Earth...

 system. It was defined as having the following coordinates:

Latitude:	3° 12' 43.2" South
Longitude:	5° 12' 39.6" West

Later the coordinate system became even more precisely defined using the Lunar Laser Ranging Experiment

Lunar laser ranging experiment

The ongoing Lunar Laser Ranging Experiment measures the distance between the Earth and the Moon using laser ranging. Lasers on Earth are aimed at retroreflectors planted on the moon during the Apollo program, and the time for the reflected light to return is determined...

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 Mösting.
