Coulomb (crater)
Encyclopedia
Coulomb is a lunar
impact crater
that lies behind the northwestern limb, on the far side of the Moon
. It is located to the west-southwest of the large crater Poczobutt
, and northeast of Sarton
.
The rim of this crater is mildly eroded, but still retains a well-defined edge and displays some old terracing on the wide inner walls. The exterior of the crater also retains something of an outer rampart, extending for about a third of crater diameter. The satellite crater Coulomb V lies just beyond the west-northwest limb, while on the opposite side Coulomb J lies a short distance from the outer rim, forming a nearly symmetric pattern. The inner walls of the crater have only a few small impacts along the sides, with one near each of the aforementioned satellite craters.
Within the sloping inner walls, the crater floor is remarkably level and nearly featureless, at least in comparison to the more rugged terrain that surrounds the crater. Only a few tiny craterlets mark this interior plain, and a small crater near the south-southeast 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...

Poczobutt (crater)
Poczobutt is a large lunar impact crater that is located on the far side of the Moon, just beyond the northwestern limb in an area occasionally brought into sight due to libration effects. This is a damaged formation that is partly overlain by several named craters. Across the rim to the...

Sarton (crater)
Sarton is a lunar impact crater that lies beyond the northwestern limb of the Moon, on the far side from the Earth. It is located to the southwest of the crater Coulomb, to the north of the walled plain Landau. Nearly attached to the northwestern rim is the smaller Weber.Although roughly circular,...

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 Coulomb.| Coulomb | Latitude | Longitude | Diameter |
