Humboldt is a large lunar impact crater that is located near the eastern limb of the Moon. Due to foreshortening this formation has an extremely oblong appearance. The actual shape of the crater is an irregular circle, with a significant indentation along the southeastern rim where the prominent crater Barnard intrudes. To the north-northwest of Humboldt is the large crater Hecataeus. Phillips is attached to the western rim. The rim of Humboldt is low, worn, and irregular in outline. The central peak forms a range on the crater floor. The floor surface contains a network of rilles forming a pattern of radial spokes and concentric arcs. There are also some dark patches located near the walls to the northeast, northwest, and southeast. There is a chain of craters leading from the northwest crater rim to a distance almost as long as the crater is wide. This formation is designated Catena Humboldt. Due to its location near the lunar limb, little detail was known about this crater until it was photographed by orbiting spacecraft.
Avicenna is a lunar impact crater that lies on the far side of the Moon, just beyond the western limb on the northern rim of the Lorentz basin. It is named after the Persian polymath Avicenna. It lies to the north-northwest of the larger crater Nernst, and to the southeast of Bragg.
Bilharz is a lunar impact crater that lies in the eastern part of the Mare Fecunditatis. It is the largest member of a close triple-crater formation with Atwood to the east and Naonobu to the northeast. To the southeast is the crater Langrenus.
Bridgman is a lunar impact crater that is located on the far side of the Moon. It lies in the northern hemisphere, to the northwest of the crater Kurchatov. To the west-southwest is the old formation Becquerel, and eastward are the craters Pawsey and Wiener.
Becquerel is a lunar impact crater that lies in the northern hemisphere on the far side of the Moon. This is an ancient and heavily worn formation that is now little more than an irregular buri in the surface. The outer rim has been worn and reshaped until it forms a rugged, mountainous region around the flatter interior.
Bunsen is a lunar impact crater that lies near the northwestern limb of the Moon. It is located to the west of the Oceanus Procellarum and the crater von Braun. To the southeast is the crater Lavoisier, and to the northeast lies Gerard. Northwest of Bunsen, on the far side of the Moon, is McLaughlin. Due to its position this crater appears foreshortened when viewed from the Earth, and its visibility is affected by libration.
Moore is an impact crater that is located on the far side of the Moon. Like much of the far side, Moore is located in a region that has been saturated by impacts. Nearby craters of note are Larmor to the south-southwest, and Parsons about the same distance to the west.
Sumner is a lunar impact crater on the far side of the Moon, beyond the northeastern limb. It is southwest of the larger crater Szilard, and southeast of the twin walled plains Fabry and Harkhebi.
Mendeleev is a large lunar impact crater that is located on the far side of the Moon, as seen from the Earth. The southern rim of this walled plain just crosses the lunar equator. Intruding into the eastern rim of Mendeleev is the crater Schuster. Nearly on the opposite side, the smaller Hartmann intrudes into west-southwestern rim.
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.
D'Arsonval is a small lunar impact crater on the far side of the Moon. It is situated across the northeastern rim of the older and larger crater Danjon. To the west of D'Arsonval is Perepelkin.
Delporte is a lunar impact crater on the far side of the Moon. It overlies part of the northwestern rim of the huge walled plain Fermi, and the crater Litke is nearly attached to the southeastern rim.
Dobrovolʹskiy is a small lunar impact crater on the Moon's far side. The northwest part of its rim is intruded upon by the somewhat larger crater Shirakatsi, and the outer rampart of that feature covers most of the interior floor of Dobrovolʹskiy. Very little of the original floor now survives, with a small section near the southern inner wall. The remainder of the crater rim is somewhat circular and only mildly worn.
Dunér is an old lunar impact crater that is located in the northern hemisphere on the far side of the Moon. It lies to the southeast of the crater Chernyshev, and west-southwest of the Perkin–Debye crater pair.
Harriot is a lunar impact crater that is located on the far side of the Moon from the Earth. It lies just to the north of the much larger crater Seyfert. To the northeast of Harriot is the crater Cantor. About one and a half crater diameters to the north of Harriot is the eastern end of a crater chain named Catena Sumner. This feature continues to the west-northwest for a distance of 247 km, passing to the north of the crater Sumner.
Gregory is a lunar impact crater on the far side of the Moon. It is located to the southeast of the crater Ibn Firnas, and north-northeast of Bečvář. About one crater diameter to the north is the smaller Morozov.
Trumpler is a lunar impact crater on the far side of the Moon. It was named by the IAU in 1970 after Swiss-American astronomer Robert Julius Trumpler (1886–1956). It lies just to the south of the crater Nušl, and northwest of Freundlich. To the southwest is the heavily battered crater Tikhomirov.
Wiener is a lunar impact crater that lies on the Moon's far side. It is located just to the southwest of the larger crater Campbell. To the southwest of Wiener is the heavily worn Kurchatov. To the east along the rim of Campbell is Von Neumann. The smaller crater Pawsey lies to the north-northwest, and is partly overlain by the outer rampart of Wiener.
Möbius is a lunar impact crater that is located on the Moon's far side, beyond the eastern limb and northeast of the Mare Marginis. It lies less than one crater diameter to the northwest of the larger, 90-km-diameter Hertz, and just to the southeast of Popov. To the north of Mobius is the crater chain designated Catena Dziewulski, which takes its name from the crater Dziewulski to the north-northwest.
Prager is an impact crater on the Moon's far side. It is located just to the northeast of the crater Love. Farther to the south-southeast lies Lane. To the north of this crater and leading away to the northwest is a crater chain that has been designated Catena Gregory.
