Engel'gardt (crater)
Encyclopedia
Engel'gardt is a lunar
crater
on the far side of the Moon
, located to the north of the huge walled plain Korolev
. The satellite crater Engel'gardt B is attached to the north rim of this crater, and is actually a much larger formation with a diameter of 163 km. To the west-northwest is the crater Lebedinskiy
.
This is a circular crater with a rim that has been only mildly eroded. The material on the inner sides has slid down to form piles of scree along the base. The inner wall is narrowed to the south, where the satellite crater Engel'gardt N lies adjacent to the edge. Less than a crater diameter to the east-southeast is a small crater with a high albedo
surrounded by a skirt of light surface. This skirt reaches to the edge of Engel'gardt's rim.
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...

Korolev (lunar crater)
Korolev is a large lunar crater of the walled plain type, named for Soviet rocket engineer Sergey Korolyov. It lies on the far side of the Moon, and the northern part of its floor crosses the lunar equator...

Lebedinskiy (crater)
Lebedinskiy is an impact crater on the far side of the Moon. It is attached to the eastern outer rim of the somewhat larger crater Zhukovskiy. About two crater diameters to the east-southeast lies the smaller Engel'gardt...
