Louville is a 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...

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...

 that is located on the western edge of the Sinus Roris

Sinus Roris

Sinus Roris is an extension of the northern edge of Oceanus Procellarum on the Moon. The IAU-defined selenographic coordinates of this bay are 54.0° N, 56.6° W, and the diameter is 202 km....

Oceanus Procellarum

Oceanus Procellarum is a vast lunar mare on the western edge of the near side of the Earth's Moon. Its name derives from the old superstition that its appearance during the second quarter heralded bad weather...

. It lies to the northwest of the crater Mairan

Mairan (crater)

Mairan is a lunar impact crater that is located on a highland peninsula between Oceanus Procellarum to the west and Mare Imbrium to the east. To the north-northeast is the comparably sized crater Sharp. Northwest of Mairan is the heavily eroded Louville....

, on a triangular section of continental terrain to the west of Sinus Iridum

Sinus Iridum

Sinus Iridum is a plain of basaltic lava that forms a northwestern extension to the Mare Imbrium. It is surrounded from the northeast to the southwest by the Montes Jura range. The protruding part of the range at the southwest end is named Promontorium Heraclides, while that at the northeast end...

 and the Mare Imbrium

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...

.

This crater formation has been heavily eroded by impacts, to the point where the surface is somewhat difficult to distinguish from the surrounding rugged terrain to the east. It is now an irregular depression in the surface, with worn, uneven features. The small crater Louville B lies along the western rim, while Louville A lies just to the southeast.

To the west across the lunar mare is a long, slender rille

Rille

Rille is typically used to describe any of the long, narrow depressions in the lunar surface that resemble channels. Typically a rille can be up to several kilometers wide and hundreds of kilometers in length...

designated Rima Sharp. This follows a generally north–south route, beginning to the north-northwest of Louville and continuing until it terminates to the south-southwest. The total diameter of this formation is 107 km.

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 Louville.
