Papaleksi is an 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...

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 lies along the northeastern outskirts of the large crater Mandel'shtam

Mandel'shtam (crater)

Mandel'shtam is the remains of a large crater on the Moon's far side. Nearly attached to the northeast outer rim is the crater Papaleksi. To the south lies the crater Vening Meinesz....

. About 20 km to the north-northeast of Papaleksi is the similar crater Spencer Jones

Spencer Jones (crater)

Spencer Jones is a lunar impact crater on the Moon's far side. It is a roughly circular feature with a rim edge that is only moderately eroded. The inner wall of Spencer Jones is wider than elsewhere. The interior floor is relatively level with a low ridge offset to the south of the mid-point...

.

This is a roughly circular crater with an eroded outer rim that has lost much of its original sharp definition. Much of the original structure of the rim and inner walls have been worn down, but only three small craters lie along the rim edge to the southwest. There is a central ridge near the mid-point with an impact at the east end, and a linear arrangement of small impacts to the south of this ridge. A small crater lies along the edge of the northern inner wall.

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 Papaleksi.
