Zsigmondy is a lunar impact crater located beyond the northwestern limb on the far side of the Moon. Attached to the southeastern rim of the crater is the crater Omar Khayyam, which lies within the much larger Poczobutt. Farther to the east, along the north rim of Poczobutt, is Smoluchowski.
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.
Boss is a lunar impact crater that is located along the northeast rim of the Moon's near side. Due to its location, the crater is viewed from the side by observers on the Earth, and its visibility is subject to libration effects.
Belʹkovich is a large lunar impact crater of the form termed a walled plain. The formation has been heavily eroded by a history of subsequent impacts, leaving it reshaped, worn, and the features softened and rounded. Belʹkovich is located along the northeastern limb of the Moon, and so its visibility is subject to libration effects. From the Earth this crater is viewed from the side, making it difficult to view it in detail.
Klaproth is an old lunar impact crater that lies in the rugged southern highlands of the Moon's near side. Due to its location, this crater appears significantly foreshortened when viewed from the Earth. The southern rim of the crater is overlain by the similar-sized crater Casatus, and to the north-northeast lies Blancanus.
Perrine is a lunar impact crater that is located on the northern hemisphere on the far side of the Moon. It lies to the west of the large walled plain Landau, and to the northeast of the crater Charlier. To the north-northwest is the smaller Gullstrand.
Crocco is a lunar impact crater that is located on the far side of the Moon from the Earth. It is located to the northeast of the huge walled plain Planck, and northwest of the equally huge Poincaré. Just to the north, within one crater diameter, is the crater Koch.
Harkhebi is a large lunar impact crater of the category termed a walled plain, on the far side. Half of the crater to the north-northeast is overlain by the walled plain Fabry, a large formation in its own right. Attached to the northwestern rim is the much smaller crater Vashakidze. To the southwest lies Vestine, and to the south is Richardson.
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 north-northeast is the crater Smoluchowski. The crater Zsigmondy overlies the northeastern rim, and Omar Khayyam is located in the western part of Poczobutt's interior.
Chappell is a lunar impact crater on the far side of the Moon, in the northern hemisphere just to the north of the crater Debye. It is in a heavily bombarded section of the surface, and much of its outer rim is overlain by smaller craters. The northern rim in particular has been almost completely disintegrated, while small craters also overlie the rim to the northwest and southeast. What remains of the rim forms a rounded, somewhat irregular edge to the crater depression.
Nonius is a lunar impact crater. It is located in the rugged southern highlands on the Moon's near side. It was named after 16th century Portuguese mathematician Pedro Nunes, Latinized as Nonius. The northwestern side and about half the interior floor are overlain by the rim and outer rampart of the walled plain Walther. About half its diameter to the southeast is the smaller crater Kaiser, and slightly farther to the south lies Fernelius.
Vega is an eroded lunar impact crater that is located in the southeastern part of the Moon. It lies on the near side and so can be viewed from the Earth. Less than one crater diameter to the east-southeast is the slightly smaller Peirescius. About one and a half crater diameters to the west is the long Vallis Rheita.
Idelʹson is a lunar impact crater that is located on the far side of the Moon. It lies just behind the southern lunar limb, in a region that is sometimes brought into view of the Earth due to libration. Idel'son is situated to the southwest of the huge walled plain Schrödinger.
Mach is a large lunar impact crater of the class known as a walled plain. It is located on the far side of the Moon and cannot be viewed directly from the Earth. Nearby craters of note include Joule to the northeast, Mitra attached to the western outer rim, and Henyey to the southwest.
Rynin is a lunar impact crater that is located just behind the northwestern limb, on the far side of the Moon. It is located just to the east of the larger crater Stefan, and to the southwest of Chapman.
Stefan is a lunar impact crater on the far side of the Moon, just beyond the northwestern limb. Attached to the western rim is the slightly smaller crater Wegener, and close to the eastern rim is Rynin.
Mandelʹshtam is the remains of a large crater on the Moon's far side named after Leonid Mandelstam. Nearly attached to the northeast outer rim is the crater Papaleksi. To the south lies the crater Vening Meinesz.
Richardson is a large lunar impact crater located on the Moon's far side, just behind the eastern limb. It lies to the south of the huge walled plain Harkhebi, and to the east-southeast of the crater Vestine. Just to the northeast is Szilard, and to the southeast is Artamonov.
Lodygin is a lunar impact crater to the southeast of the much larger crater Galois. To the east-northeast is the crater Paschen, and to the south-southwest is the immense Apollo.
Röntgen is a relatively large lunar impact crater that lies along the northwestern limb of the Moon. Its northwestern outer rim is partly overlain by the crater Nernst. Both Nernst and Röntgen overlie the eastern rim of the much larger walled plain Lorentz. The smaller crater Aston is separated from the eastern edge of Röntgen by only a few kilometers of terrain. To the south-southeast is Voskresenskiy.
