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.
Cardanus is a lunar impact crater that is located in the western part of the Moon, in the western part of the Oceanus Procellarum. Due to its location the crater appears very oval because of foreshortening, and it is viewed almost from the side.
Almanon is a lunar impact crater that lies in the rugged highlands in the south-central region of the Moon. It was named after Abbasid Caliph and astronomer Al-Ma'mun. It is located to the south-southeast of Abulfeda, and to the north-northeast of the smaller crater Geber. The crater chain designated Catena Abulfeda forms a line between the south rim of Abulfeda and the north rim of Almanon, continuing for a length of about 210 kilometers to the Rupes Altai scarp.
Arrhenius is a lunar impact crater that is located just on the far side of the Moon, near the southwest limb. In this location the vicinity of the crater can be viewed during favorable librations, although it is viewed from on edge. To the south-southeast is the worn crater Blanchard, and De Roy lies further to the west.
Artamonov is a lunar impact crater on the far side of the Moon. Its eroded outer rim does not have the circular shape of most lunar craters, but the overall shape of three or four merged craters. The largest is in the south, with smaller circular bulges to the north and east.
Davy is a small lunar impact crater that is located on the eastern edge of the Mare Nubium. It was named after British physicist Humphry Davy. It overlies the lava-flooded remains of the satellite crater Davy Y to the east, a formation which contains a crater chain designated Catena Davy. To the southeast of Davy is the prominent crater Alphonsus.
Boole is a lunar impact crater that lies along the northwestern limb of the Moon, to the northwest of the crater Gerard. At this location it is viewed nearly from the side, and is very oblong in shape due to foreshortening. The crater formation is nearly circular, however, with a wide inner wall that has been worn and rounded due to subsequent impacts. It is named after George Boole.
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.
Fabry is a large lunar impact crater of the form termed a walled plain. It is located on the far side of the Moon, just beyond the northeastern limb. Parts of this area are sometimes brought into view by the effects of libration, but the terrain is seen from the edge and so not much in the way of detail can be observed.
Bečvář is a lunar impact crater that is located near the equator on the far side of the Moon. It lies to the northeast of the crater Necho, within that feature's ray system. To the north-northeast is the crater Gregory.
Drygalski is a large lunar impact crater that lies along the southern limb of the Moon. It partly overlies the crater Ashbrook to the west on the far side of the Moon. Just to the north of Drygalski is the smaller Boltzmann. The location of this crater restricts its observation from the Earth, and even under conditions of favorable libration it is viewed from the edge. It is only illuminated by the Sun at an oblique angle, and it lies close to the south polar craters that are permanently shielded from sunlight.
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.
Gibbs is a lunar impact crater that lies near the eastern limb of the Moon. It is situated less than a crater diameter to the northeast of the larger crater Hecataeus. The crater chain Catena Humboldt passes to the south of Gibbs, following a line to the northeast. Due to its proximity to the limb, this crater appears foreshortened when viewed from the Earth, and visibility is subject to libration.
Dziewulski is a lunar impact crater on the far side of the Moon. It lies between the craters Edison to the north and Popov to the south. The outer rim of this crater has been considerably worn by impacts, particularly along the southwest quadrant where the satellite crater Dziewulski Q overlies the rim and the interior floor. The northern rim is also heavily disrupted, and several small crater lie along the southeast rim. The interior floor and surrounding terrain has been resurfaced.
Dellinger is a lunar impact crater that is located on the Moon's far side. It is attached to the southern rim of the crater Pannekoek. To the southeast lies the crater Marconi, and to the southwest is Chauvenet.
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.
Kurchatov is a lunar impact crater that is located on the Moon's far side. It is just to the southwest of the crater Wiener, and farther to the southeast of Bridgman. A couple of crater diameters to the south of Kurchatov is the northern edge of the Mare Moscoviense.
Love is an impact crater on the far side of the Moon. It is located just to the north of the crater Perepelkin. Prager nearly touches the northeastern rim. To the northwest is Bečvář.
Michelson is a crater on the far side of the Moon. It lies along the northeastern outer rim of the huge walled plain Hertzsprung, and to the southwest of the crater Kolhörster.
