Dalton (crater)
Encyclopedia
Dalton is a lunar
impact crater
that is located near the western limb of the Moon
's near side. It is attached to the eastern rim of the walled plain Einstein
, with Balboa
lying just to the north and Vasco da Gama
due south. The rim of this crater is not heavily eroded, and the interior walls are terraced. The interior floor has a system of rille
s that are generally concentric with the inner wall. There is a small crater near the southern inner wall, and another at the north face of the small central peak.
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...

Einstein (crater)
Einstein is a large lunar crater that lies along the western limb of the Moon, making it difficult to observe from the Earth. The visibility of this formation is affected by libration effects, but even under the best conditions not much detail can be observed except from lunar orbit...

Balboa (lunar crater)
Balboa is a lunar crater that is located near the western limb of the Moon. Due to foreshortening, the crater appears highly oval when viewed from the Earth. In actuality, however, the formation is relatively circular. It is comparable in size to the crater Dalton, located just to the southwest...

Vasco da Gama (crater)
Vasco da Gama is a lunar impact crater that is located near the western limb of the Moon. It is named for the Portuguese explorer Vasco da Gama. It lies to the south of the walled plain Einstein, due south of Dalton...

Rille
Rille is typically used to describe any of the long, narrow depressions in the lunar surface that resemble channels. Typically a rille can be up to several kilometers wide and hundreds of kilometers in length...
