Fersman (crater)
Encyclopedia
Fersman is a large lunar
impact crater
on the Moon
's far side. It lies to the east of the crater Poynting
, and west-northwest of Weyl
. To the south is the huge walled plain Hertzsprung
.
This is a worn crater with a low, outer rim. The southeast rim and the eastern interior floor are marked by ejecta deposits that trend from southeast to northwest. There is also a nearly linear series of small craters that begin to the southeast of the crater, and continue about 100 km to the northwest of the crater. There is a break in this chain across the crater's interior floor, then it continues again near the northern rim.
Several other small craters lie across the interior floor, including a grouping to the south of the mid-point. The rim has an outward bulge along the southeast side and irregular edges to the north and south. A small crater lies along the western inner wall.
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...

Poynting (lunar crater)
Poynting is a large lunar impact crater located on the far side of the Moon. It is located to the north-northwest of the walled plain Hertzsprung, with the crater Fersman immediately to the east and Kekulé equally near to the west-southwest....

Weyl (crater)
Weyl is a lunar impact crater that is located on the far side of the Moon, behind the western limb as seen from the Earth. It lies to the east-southeast of the larger crater Fersman. To the southeast is Kamerlingh Onnes, and to the northeast is Shternberg....

Hertzsprung (crater)
Hertzsprung is an enormous lunar crater that is located on the far side of the Moon, beyond the western limb. In dimension, this formation is larger than several of the lunar mare areas on the near side. It lies in the northwestern fringe of the blast radius of the Mare Orientale impact basin...
