Eponym Alexander Friedmann

Fridman is the remains of a lunar impact crater on the far side of the Moon. It lies due south of the huge walled plain Hertzsprung, and is attached to the northeastern rim of the crater Ioffe.

This crater lies in the southern part of the ejecta blanket that encircles Hertzsprung, and in the west-northwestern part of the huge ejecta blanket surrounding the Mare Orientale impact basin. The outer rim of this crater is heavily damaged, with a number of smaller craters lying across the sides. The most intact portion of the rim is along the southeastern side.

The southwestern interior floor is partly overlaid by the outer rampart of Ioffe. The northern floor is marked by several small craters, while the southeastern floor is impacted by a number of tiny craterlets.

This crater is called Friedmann in some sources.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Fridman.

Aitken (crater)

Aitken is a large lunar impact crater that lies on the far side of the Moon, named for Robert Grant Aitken, an American astronomer specializing in binary stellar systems. It is located to the southeast of the crater Heaviside, and north of the unusual formation Van de Graaff. Attached to the southwest rim is Vertregt. To the southeast is the smaller Bergstrand.

Ashbrook (crater)

Ashbrook is a large lunar impact crater that is located in the vicinity of the south pole on the far side of the Moon, and so cannot be viewed directly from the Earth. The eastern face of the crater has been overlain by the similar-sized Drygalski, and more than half the interior floor of Ashbrook is covered by the outer ramparts and ejecta of Drygalski. To the northwest is the walled plain Zeeman.

Fechner (crater)

Fechner is a lunar impact crater that lies on the far side of the Moon's southern hemisphere, attached to the western rim of the large walled plain Planck. The eastern rim of Fechner intersects the Vallis Planck, a long, wide cleft in the surface that follows a course to the north-northwest. This valley intrudes into the southeastern rim of the crater, then continues northwards from the periphery of the northeast rim.

Barringer (lunar crater)

Barringer is a lunar impact crater that is located on the southern hemisphere on the Far side of the Moon, named after geologist Daniel Barringer. It is attached to the north-northeastern rim of the walled basin named Apollo, and lies to the southeast of Plummer. South of Barringer, on the floor of the Apollo basin, is the crater Scobee.

Blackett (crater)

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.

Chant (crater)

Chant is a lunar impact crater that is located on the far side of the Moon, behind the southwest limb as seen from the Earth. It lies within the southwestern part of the blanket of ejecta surrounding the Mare Orientale, beyond the Montes Cordillera mountain ring. To the west-northwest is the large walled plain Blackett. Southward is the crater Mendel.

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.

Hertzsprung (crater)

Hertzsprung is an enormous lunar impact crater, or impact basin, that is located on the far side of the Moon, beyond the western limb. In dimension, this formation is larger than several of the lunar mare areas on the near side. It lies in the northwestern fringe of the blast radius of the Mare Orientale impact basin. Nearby craters of note include Michelson across the northeast rim, Vavilov across the western rim, and Lucretius to the southeast.

Hartwig (lunar crater)

Hartwig is a lunar impact crater that is located near the western limb of the Moon. It is attached to the eastern rim of the prominent crater Schlüter, to the northeast of the Montes Cordillera mountain range that surrounds the Mare Orientale. To the east-northeast of Hartwig is the larger crater Riccioli.

Chaucer (crater)

Chaucer is a lunar impact crater that is located to the west of the walled plain Hertzsprung, on the far side of the Moon. It lies to the northwest of the crater Vavilov and east of the Tsander–Kibal'chich crater pair. This is a circular crater with a slightly eroded outer rim. The interior floor is nearly featureless, with only a few tiny craterlets marking the surface. It is named after the writer Geoffrey Chaucer.

Graff (lunar crater)

Graff is a small lunar impact crater that lies along the southwestern limb of the Moon. It is located to the west of the Vallis Bouvard depression in the southern part of the ejecta blanket that surrounds the Mare Orientale impact basin. To the south-southwest is the smaller crater Catalán.

Elvey (crater)

Elvey is a lunar impact crater that is located on the far side of the Moon. It is located near the northern edge of the blanket of ejecta that surrounds the Mare Orientale impact basin. To the north of Elvey is the smaller crater Nobel.

Evans (crater)

Evans is the remnant of a lunar impact crater that is located on the far side of the Moon. It lies to the south-southwest of the immense walled plain Hertzsprung, and is located within that impact basin's broad skirt of ejecta. This material has overflowed the northern rim of Evans and the northern part of the interior floor. The southern rim is not as heavily damaged, although it is irregular, eroded, and overlain by a pair of small craterlets. The most intact part of the rim is the southeastern section.

Gerasimovich (crater)

Gerasimovich is a lunar impact crater on the far side of the Moon. It lies beyond the western limb, to the west-northwest of the immense Mare Orientale impact basin. The outer blanket of ejecta from this impact reaches nearly to the rim of Gerasimovich. Nearby craters of note include Houzeau to the north and the smaller Ellerman to the southeast.

Houzeau (crater)

Houzeau is a lunar impact crater on the far side of the Moon. It is located to the northwest of the Mare Orientale impact basin, and ejecta from that event has fallen across this crater rim and its interior. To the south of Houzeau lies the crater Gerasimovich, and one crater diameter to the west is Belopol'skiy. To the northwest lies Fridman, with Ioffe to its southwest.

Ioffe (crater)

Ioffe is a lunar impact crater on the far side of the Moon. It lies to the south of the walled plain Hertzsprung, and is attached to the southwestern outer rim of Fridman. Only a short stretch of terrain separates Ioffe from Belopol'skiy to the southeast.

Kekulé (crater)

Kekulé is a lunar impact crater on the far side of the Moon. It lies just to the west-southwest of the larger crater Poynting, on the edge of the ejecta skirt surrounding the walled plain Hertzsprung to the southeast.

Paschen (crater)

Paschen is a lunar impact crater on the far side of the Moon. The relatively large satellite crater Paschen M partly overlies the southern rim of Paschen, and they nearly form a merged pair with only a section of irregular terrain along their common border. The smaller but well-formed crater Paschen S lies across the southwestern rim of Paschen. As a result, most of the southern rim of Paschen is now gone.

Wan-Hoo (crater)

Wan-Hoo is a lunar impact crater that is located on the Moon's far side, and it cannot be seen directly from the Earth. It lies to the southwest of the huge walled plain Hertzsprung, within the outer skirt of ejecta. Just to the south-southwest of Wan-Hoo is the larger crater Paschen, and a little over two crater diameters to the northwest is Sechenov.

Lucretius (crater)

Lucretius is an impact crater on the far side of the Moon. It is located to the southeast of the huge walled plain Hertzsprung, within the outer skirt of ejecta that surrounds that impact feature. To the southwest of Lucretius lies Fridman.
