Ricco (crater)
Encyclopedia
Ricco is a lunar
impact crater
. It is located in the northern part of the Moon
's far side. This crater overlies the southeastern rim of the larger crater Milankovic
. Less than one crater diameter to the southwest is Karpinskiy
, while to the southeast is Roberts
.
This is a relatively fresh crater formation that has not been degraded through impact erosion. The rim edge is well-defined except along the southwestern edge. Along that side skirt of ejecta from Karpinsky overlies the edge and the inner wall, reaching to the edge of the interior floor. The remainder of the inner wall has a slumped in places, forming a steep top section and shelves or terraces of slumped material. The most extensive terraces occur along the northwestern side, where the rim overlays part of Milankovic. The outer rampart of Ricco spills over to form a pile covering a quarter of the interior of Milankovic's floor.
The interior floor of Ricco has level patches surrounding a formation of ridges about the mid-point. The most prominent of these ridges lies along the northeast side of the mid-point. There is a smaller ridge to the south and a low ridge in the northern floor. Several low hills lie across the crater floor.

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...

Milankovic (lunar crater)
Milankovic is a lunar crater that is located in the high northern latitudes on the far side of the Moon. Overlapping the southeastern rim is the smaller but more sharply defined crater Ricco. Just to the south is Karpinskiy, and to the north is the prominent Plaskett.This is a worn and eroded...

Karpinskiy (crater)
Karpinskiy is a lunar impact crater that lies in the northern part of the Moon on the far side from the Earth. This crater is concentric with a larger and older formation lying along the southern rim. This combined rim gives Karpinskiy a larger and wider interior wall along its south face...

Roberts (crater)
Roberts is a lunar impact crater that is located in the far northern latitudes on the far side of the Moon. It is located to the east-southeast of the crater Karpinskiy, and to the northwest of Sommerfeld. To the north is Thiessen....
