Kramers (crater)
Encyclopedia
Kramers is an old lunar
crater
that is located on the northern hemisphere
on the far side of the Moon
. It lies some distance to the west of the larger crater Coulomb
, and to the northwest of the smaller Weber
.
The outer rim of Kramers is heavily eroded and worn, although the perimeter of the original crater can be readily discerned. The younger, but comparably sized formation Kramers C intrudes into the northeast rim, and the two form a crater pair. The later crater has a terraced inner wall and a central peak at the mid-point.
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...

Sphere
A sphere is a perfectly round geometrical object in three-dimensional space, such as the shape of a round ball. Like a circle in two dimensions, a perfect sphere is completely symmetrical around its center, with all points on the surface lying the same distance r from the center point...

Weber (crater)
Weber is a lunar impact crater on the far side of the Moon, and it cannot be viewed directly from the Earth's surface. This crater is attached to the northwest outer rim of the larger crater Sarton...

Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Kramers.| Kramers | Latitude | Longitude | Diameter |
