Shi Shen (crater)
Encyclopedia
Shi Shen is a crater
on the far side of the Moon
. It lies to the northwest of the large walled plain Schwarzschild
, and to the south-southeast of the crater Nansen
along the north-northeastern limb. Shi Shen is located in the region of the lunar surface that is sometimes brought into view of the Earth due to libration
, but even then it is viewed from the edge and not much detail can be seen.
This is an old, eroded crater with an outer rim that is rounded and somewhat irregular. The northern part of the rim has a wider inner wall, and there is a small crater along the north-northwestern edge. The interior floor is relatively level, but uneven, particularly in the northern half.
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...

Nansen (lunar crater)
Nansen is an old lunar crater along the northern limb of the Moon, on the eastern side of the north pole. This feature is viewed from the edge from the Earth, and it must be observed from orbit to see much detail...

Libration
In astronomy, libration is an oscillating motion of orbiting bodies relative to each other, notably including the motion of the Moon relative to Earth, or of Trojan asteroids relative to planets.-Lunar libration:...
