Cockcroft (crater)
Encyclopedia
Cockcroft is a lunar
crater
that is situated on the far side of the Moon
from the Earth
, so that it has only be observed and photograph
ed from orbit
. It lies to the northeast of the larger crater Fitzgerald
, and southeast of Evershed
.
The rim of this crater is worn and eroded from subsequent impacts. The satellite crater Cockroft N is intruding into the south-southwestern rim. There are small craters along the rim to the southeast, east, and north-northwest, and a small crater lies along the eastern inner wall. The interior floor is uneven in places, particularly in the southern half, and contains multiple small and 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...

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...

Photograph
A photograph is an image created by light falling on a light-sensitive surface, usually photographic film or an electronic imager such as a CCD or a CMOS chip. Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of...

Orbit
In physics, an orbit is the gravitationally curved path of an object around a point in space, for example the orbit of a planet around the center of a star system, such as the Solar System...

Evershed is a lunar impact crater on the far side of the Moon, named after the English solar astronomer John Evershed. It is located to the northeast of the larger crater Cockcroft, and to the north of the smaller Van den Bergh....
