Moretus is a lunar impact 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...

 located in the heavily cratered highland region near the south pole 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...

. South of it is the crater Short

Short (crater)

Short is a lunar impact crater that is located in the southern regions of the Moon, on the near side. It lies just to the south of the larger, prominent crater Moretus, and northeast of Newton....

, while to the north is Cysatus

Cysatus (crater)

Cysatus is a lunar impact crater that is located in the southern part of the Moon's near side. It is joined to the norhteastern rim of the larger crater Gruemberger, and intrudes slightly into the interior of that formation. Due south is the larger Moretus, and to the east is Curtius...

. To the northwest lies Gruemberger, and Curtius

Curtius (crater)

Curtius is a lunar impact crater that is located in the southern part of the Moon. From the Earth the crater appears foreshortened, making it more difficult to observe detail. Nevertheless this is a large crater that can be readily found in even small telescopes. Curtius is located within one...

 is located to the northeast. Due to the location near the lunar limb, the crater appears oblong because of foreshortening.

The rim of the crater has a wide, terraced inner wall, and a complex outer rampart. The floor has been partly resurfaced and is relatively flat. In the middle is a central mountain formation that rises about 2.1 kilometers above the surrounding floor.

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 Moretus.
