Von Neumann (crater)
Encyclopedia
Von Neumann is a lunar
impact crater
that lies on the far side of the Moon
, in the northern hemisphere. It is nearly attached to the south-southeastern rim of the walled plain Campbell
. The crater Ley
is attached to the northeastern rim of Von Neumann, and is somewhat overlain by the outer rampart. To the west is the prominent Wiener
, and to the south-southwest is Nikolayev
.
This crater has a wide inner wall with multiple terraces. The width of the inner wall varies around the perimeter, with the widest section to the south. There is some slumping along the inner wall to the northwest where the rim makes its closest approach to Campbell, and the narrow terrain between these two craters is rugged and irregular. But the remaining terrain that surrounds the crater is almost equally rugged. The rim appears somewhat straighter along the southwest side, but is roughly circular elsewhere.
The interior floor is nearly flat and level along the western side. There is a small range of ridges running from the south to the northern edge of the floor, and the ground is more irregular in the eastern half. There are no significant impacts within the crater interior and the sides are generally unworn.

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...

Campbell (lunar crater)
Campbell is a large lunar crater that is located in the northern hemisphere on the far side of the Moon. It lies to the southwest of the walled plain D'Alembert, an even larger formation. If Campbell were located on the near side of the Moon as seen from the Earth, it would form one of the largest...

Ley is a lunar impact crater that is located across the southern rim of the much larger walled plain Campbell. Intruding into the south-southwestern rim of Ley is the slightly larger crater Von Neumann....

Wiener is a lunar impact crater that lies on the Moon's far side. It is located just to the southwest of the larger crater Campbell. To the southwest of Wiener is the heavily worn Kurchatov. To the east along the rim of Campbell is Von Neumann...

Nikolayev (crater)
Nikolaev is a crater on the far side of the Moon. It is located north of the Mare Moscoviense and south of the larger crater Von Neumann. Because it is on the far side of the Moon, it is not visible from Earth....
