Poynting (lunar crater)
Encyclopedia
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.
This crater has undergone some erosion, and several small craters lie across the rim and inner wall. A pair of these lie next to each other along the eastern side, and another pair on the western rim. Across the southeast rim is a nearly merged crater pair. Parts of the rim remain well-defined, however, including the east and north where there are some terraces. The rim is generally circular, with a slight inward intrusion along the northwest.
The interior floor is relatively level, except for a central peak ridge located slightly to the east of the mid-point. There are small craterlets on the floor near the south and northwest edge, and a number of tiny craterlets.
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...

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...

Fersman (crater)
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....

Kekulé (crater)
Kekulé is a lunar crater on the far side of the Moon. It lies just to the west-southwest of the larger crater Poynting, on the edge of the ejecta skirt surrounding the walled plain Hertzsprung to the southeast....
