d’Alembert (crater)

d’Alembert is a large lunar impact crater located in the northern hemisphere on the far side of the Moon, to the northeast of the somewhat smaller walled plain Campbell. Astride the southwest rim of d’Alembert is Slipher. To the north is the crater Yamamoto, and to the south-southwest lies Langevin. This walled plain has the same diameter as Clavius on the near side, making it one of the largest such

Chernyshev (crater)

Chernyshev is a lunar impact crater that is located in the northern part of the Moon’s far side. It lies to the northeast of the crater Chandler, and to the southeast of the walled plain D’Alembert. The rim of this crater has been worn by impacts, and multiple tiny craters lie along the rim. The southern part of the rim in particular has

Comrie (crater)

Comrie is a lunar impact crater. It is located on the rugged far side of the Moon relative to the Earth, beyond the western limb. Nearby craters of note include Ohm to the south-southwest, Shternberg to the southwest, and Parenago to the northeast. This feature forms the central member of a formation of three connected craters. A slightly smaller crater is attached to the northern end, and the two

Coulomb-Sarton Basin

The Coulomb-Sarton Basin is a Pre-Nectarian impact basin on the far side of the moon.[2] It is named after the crater Coulomb northeast of the center of the basin and the smaller crater Sarton just south of the center. The basin is not obvious on the lunar surface. There are only small fragments of inner rings and a rim, and the most indicative topographic feature is

Crookes (crater)

Crookes is a lunar impact crater that lies on the Moon’s far side as seen from the Earth. It lies just to the southwest of the giant crater Korolev. To the southwest of Crookes is McKellar. The rim of this crater has a relatively high albedo compared to most such formations on the Moon, and it lies at the center of a ray system. This ejecta forms a

Campbell (lunar crater)

Campbell is a large lunar impact crater that is located in the northern hemisphere on the far side of the Moon. It lies to the southwest of the walled plain D’Alembert, an even larger formation. If Campbell were located on the near side of the Moon as seen from the Earth, it would form one of the largest visible craters, being slightly larger than Schickard. It is

Cantor (crater)

Cantor is a lunar impact crater that is located on the northern hemisphere on the far side of the Moon. The outer rim of the crater has a distinctly hexagonal shape, and is slightly longer in the north–south direction. The interior walls are multiply terraced, although less so along the western rim. There is a low central peak at the midpoint of the floor. The

Carnot (crater)

Carnot is a large crater in the northern part of the Moon’s far side. It was named after Nicolas L. S. Carnot by the IAU in 1970. The outer rim of Carnot has a somewhat hexagonal form, particularly in the southern half. The northern rim has an irregular inner wall, while the southern face is terraced and has a sharper outer edge. There is

Cassegrain (crater)

Cassegrain is a lunar impact crater that is located on the far side of the Moon, beyond the southeastern limb. It lies to the southeast of the larger crater Lebedev, and to the northeast of the comparably-sized Priestley. It is named after the inventor of the Cassegrain reflector, who was later identified as most likely Laurent Cassegrain. The interior of this crater has a relatively dark-hued

Chandler (crater)

Chandler is a lunar impact crater in the northern hemisphere, on the Moon’s far side. It lies to the southeast of the large walled plain D’Alembert, and southeast of the slightly smaller Chernyshev crater. This is a heavily worn and eroded crater that is now essentially a wide, irregular depression in the rugged lunar surface. Attached to the outer south-southwest rim is the slightly smaller
