Oresme 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...

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...

Von Kármán (lunar crater)

Von Kármán is a lunar crater that is located in the southern hemisphere on the far side of the Moon. The northern third of this formation is overlain by the rim and outer rampart of the walled plain Leibnitz, forming a deep indentation in the formation...

Chrétien (crater)

Chrétien is a lunar crater that is located in the southern hemisphere on the far side of the Moon from the Earth. It lies due south of the Mare Ingenii, one of the few maria on the Moon's far side...

Mare Ingenii

Mare Ingenii is one of the few lunar mare features on the far side of the Moon. The mare sits in the Ingenii basin. This basin material is of the Pre-Nectarian epoch. The mare material located in Ingenii and the surrounding craters is of the Upper Imbrian epoch...

. This crater was believed to have formed during the Nectarian epoch

Nectarian

The Nectarian Period of the lunar geologic timescale runs from 3920 million years ago to 3850 million years ago. It is the period during which the Nectaris Basin and other major basins were formed by large impact events...

, about 4 billion years ago.

This crater has a considerably damaged outer rim that forms an uneven, irregular ring about the interior floor. By contrast, the floor of Oresme is a relatively level, featureless surface that is marked only by a few tiny craterlets and low topological features. The rim is cut across along the southeast by the satellite crater Oresme K, and a smaller crater lies along the northern rim.

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 Oresme.
