Wegener (lunar crater)
Encyclopedia
Wegener is a lunar
impact crater
that is located in the Moon
's northern hemisphere, about midway between the equator and the north pole. It lies on the far side from the Earth
, behind the northwestern limb. The southwestern rim of Wegener iintrudes slightly into the much larger walled plain Landau
. Attached to the eastern rim is the crater Stefan
.
This crater is in an intermediate stage of impact erosion, with a worn rim and some craters overlapping the edge and inner wall. The rim is generally more eroded in the northern half. A small crater lies across the western inner wall and part of the interior floor. There is a small, cup-shaped craterlet just to the east of this feature. The inner wall is wider in the southern half, leaving some irregularities on the southern half of the floor. The remainder of the interior is a nearly level and featureless plain.
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...
