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.
This is a worn crater with a low, outer rim. The southeast rim and the eastern interior floor are marked by ejecta deposits that trend from southeast to northwest. There is also a nearly linear series of small craters that begin to the southeast of the crater, and continue about 100 km to the northwest of the crater. There is a break in this chain across the crater's interior floor, then it continues again near the northern rim.
Several other small craters lie across the interior floor, including a grouping to the south of the midpoint. The rim has an outward bulge along the southeast side and irregular edges to the north and south. A small crater lies along the western inner wall.
Anderson is a lunar impact crater that is located on the far side of the Moon. It is located to the northwest of the crater Sharonov, and the satellite crater Sharanov X is attached to the southeast rim of Anderson. To the northeast is the peculiar formation Buys-Ballot, and to the east-southeast lies the larger crater Spencer Jones.
Armiński is a small lunar impact crater that is located on the far side of the Moon, to the northeast of the large walled basin Gagarin. To the northwest of Armiński is the crater Beijerinck, and to the southeast lies Cyrano.
Babbage is an ancient lunar impact crater that is located near the northwest limb of the Moon, named after Charles Babbage. It is attached to the southeastern rim of the prominent crater Pythagoras. The crater remnant named South intrudes into the southeastern floor of Babbage.
Bose is a lunar impact crater that is located on the far side of the Moon, in the southern sphere hemisphere. It lies just to the northwest of the smaller crater Bhabha, and southeast of Alder.
Chamberlin is a lunar impact crater that is located on the far side of the Moon, just past the southeastern limb. It lies to the southeast of the crater Jeans, and Moulton is attached to the southeastern rim of Chamberlin. This crater is located in a part of the lunar surface that has undergone resurfacing of crater interiors, producing dark-hued crater floors.
De La Rue is the remnant of a lunar impact crater, or possibly several merged craters, creating a formation sometimes called a walled plain. It lies in the northeastern part of the Moon on the near side, and so appears foreshortened due to its location. This formation lies to the north-northwest of the prominent crater Endymion, just beyond the eastern extreme of Mare Frigoris. The crater Strabo intrudes into the northern part of De La Rue's northern rim, and the smaller Thales is attached to the northwestern part of the wall.
Bellinsgauzen is a lunar impact crater that lies in the southern part of Moon, on the far side from the Earth. It is attached to the northern rim of the larger crater Berlage, and within a half crater diameter of Cabannes to the west. North of Bellinsgauzen is the crater Bhabha.
Blackett is a lunar impact crater that lies on the far side of the Moon, behind the southwest limb. It lies beyond the southeast outer ring of the immense Mare Orientale basin. The formation of that major feature has left Blackett deeply marked with ridge features trending from the northwest. Much of the crater has been shaped by the ejecta from Mare Orientale, particularly along the western half of the crater.
Berzelius is a lunar impact crater located in the northeast part of the Moon's near side. It lies to the southeast of the crater Franklin, and to the northwest of Geminus.
Cuvier is a lunar impact crater on the southern part of the Moon's near side. It is attached to the east-southeast rim of the unusually shaped formation Heraclitus. To the northeast is the crater Clairaut.
Demonax is a lunar impact crater near the southern limb of the Moon. This location makes the crater difficult to observe due to foreshortening. The crater is also illuminated at a very low angle, when it is in the sunlit side. Demonax lies just to the north of the crater Scott, one of the south polar formations. To the north-northwest is Boguslawsky.
Clairaut is a lunar impact crater that is located in the rugged southern highlands of the Moon's near side. It lies directly to the south of the crater Maurolycus and southeast of Barocius. Just to the southwest is Cuvier.
Dyson is a lunar impact crater, 63 kilometers in diameter, that lies on the far side of the Moon, past the northwest limb. It is located in the northern part of the surface, to the northwest of the crater Coulomb, and east of van't Hoff.
Comstock is a lunar impact crater that is located on the far side of the Moon. It lies to the northeast of the walled plain Fersman, and north of the crater Weyl.
Cockcroft is a lunar impact crater that is situated on the far side of the Moon from the Earth, so that it has only been observed and photographed from orbit. It lies to the northeast of the larger crater Fitzgerald, and southeast of Evershed.
Congreve is a lunar impact crater that is located on the far side of the Moon relative to the Earth, and lies across the lunar equator. It lies to the west-northwest of the massive walled plain Korolev. To the southeast is the crater Icarus, and due north is Zhukovskiy.
De Vries is a lunar impact crater on the far side of the Moon relative to the Earth. It lies about midway between the craters Racah to the north-northwest and Orlov to the south-southeast. An nameless walled plain lies between De Vries and Orlov, with the perimeter of this feature joining the two rims.
Erro is a lunar impact crater that lies beyond the eastern limb of the Moon, on the far side as seen from the Earth. It lies along the eastern fringes of the uneven plain that joins Mare Marginis to the northwest with Mare Smythii to the west-southwest. This part of the surface is sometimes brought into sight of observers on the Earth due to libration. However even at such times not much detail can be seen, as the surface is viewed from the edge.
Grigg is a lunar impact crater that is located on the far side of the Moon. It lies in the northern outskirts of the huge walled plain Hertzsprung, to the southwest of the crater Fersman and southeast of Poynting. The rim of this crater is generally circular, with a small impact crater intruding into the eastern edge. A small crater fills the northwestern part of the interior floor.
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.
