Denning (lunar crater)
Encyclopedia
Denning is a lunar
crater
that is located on the far side of the Moon
. It lies about midway between the craters Levi-Civita
to the south and Marconi
to the north-northeast. About two crater diameters to the southeast is the huge walled plain Gagarin
.
The rim of this worn crater is circular but somewhat irregular-edged. There is a low central rise at the mid-point consisting of at least two hills. Attached to the southwest outer rim is the larger satellite crater Denning R. About one crater diameter the southeast of Denning is a bright patch of high-albedo
surface. This patch was most likely created by a small, relatively recent impact.
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...

Levi-Civita (crater)
Levi-Civita is a lunar crater formation that lies on the far side of the Moon. It is located just to the southwest of the large walled plain Gagarin, and nearly as close to the crater Pavlov to the south-southwest. To the northwest of Levi-Civita lies the smaller crater Pirquet.This is an eroded...

Marconi (crater)
Marconi is a lunar impact crater that is located on the Moon's far side. It lies to the northwest of the large walled plain Gagarin, and to the southwest of the prominent crater Chaplygin. To the west-northwest of Marconi is the slightly larger Dellinger....

Gagarin (crater)
Gagarin is a large lunar impact crater that is located in the southern hemisphere on the far side of the Moon. To the southwest is the crater Pavlov and to the northeast lies Keeler. Closer to the rim are the craters Levi-Civita to the southwest, and Beijerinck to the north-northeast. Isaev lies...
