Ammonius is a bowl-shaped lunar impact crater with a slightly raised rim. It is located on the floor of the walled plain Ptolemaeus, about 30 kilometers northeast of the crater midpoint.
Acosta is a small lunar impact crater located just to the north of the prominent crater Langrenus, near the east edge of Mare Fecunditatis. To the west are the trio of Atwood, Naonobu, and Bilharz. Acosta is named after the Portuguese naturalist Cristóvão da Costa.
Asada is a small lunar impact crater located at the northern edge of Mare Fecunditatis, to the northeast of the crater Taruntius. It is a circular crater formation with inner walls that slope down toward a small central floor at the midpoint. Asada was designated Taruntius A prior to being named by the IAU.
Born is a small lunar impact crater located near the eastern edge of the Moon, to the northeast of the prominent crater Langrenus. It was previously designated Maclaurin Y before being named by the IAU in 1979. Maclaurin itself lies to the north.
Crile is a tiny lunar impact crater. It is roughly circular and cup-shaped, with interior walls that slope down to the midpoint. The crater lies in the Palus Somni, between the Mare Crisium to the east and Mare Tranquillitatis to the west.
Bohnenberger is a lunar impact crater that lies near the east edge of the Mare Nectaris, in the foothills of the Montes Pyrenaeus mountain range that forms the perimeter of the mare. To the east beyond the mountains is the larger crater Colombo. The crater has a low rim along the north wall, and the floor is somewhat irregular with a ridge crossing the floor. There is a small crater along the western inner wall.
De Vico is a small lunar impact crater that is located in the southwest part of the Moon, to the south of the crater Sirsalis. To the west-northwest is Crüger. De Vico is a circular, bowl-shaped formation with a small, flat bottom at the midpoint. To the northwest is the lava-flooded remains of De Vico T. Beyond is a linear rille designated Rimae Sirsalis that follows a path to the northeast past the rim of Sirsalis.
Burckhardt is a lunar impact crater that is located in the northeast part of the Moon. It lies between the craters Geminus just to the north and Cleomedes to the south.
Bell is a lunar impact crater that is located on the far side of the Moon, just past the western limb. It lies in an area of terrain that is marked by many small craters, a number of which are satellite craters of Bell listed in the table below. Bell lies within two crater diameters of Laue to the north, and to the west of the smaller Helberg.
Ball is a lunar impact crater that is located in the rugged southern highlands of the Moon. It was named after British astronomer William Ball. The formation is circular and symmetrical, and has received little significant wear. The interior is rough-surfaced, curving downward toward the relatively wide central peak at the midpoint.
Bok is a lunar impact crater that is located on the far side of the Moon. To the southeast is the crater Sniadecki; to the north is McKellar, and further to the west is De Vries.
Brunner is a lunar impact crater that is located along the eastern limb of the Moon, to the southeast of the Mare Smythii. At this location the crater is viewed from the edge, and so it is not possible to see much detail from the Earth. The visibility of this formation is also affected by libration. The crater lies to the southwest of the walled plain Hirayama, and to the east of the elongated crater Houtermans.
Buisson is a lunar impact crater that is located on the far side of the Moon. It is named after the French physicist Henri Buisson. Nearly attached to the southeast rim is the crater Vesalius. To the southwest is Einthoven. The rim of this crater is somewhat worn, and is lowest in the north. There is a low central ridge across the midpoint.
Bredikhin is a lunar impact crater that is located on the far side of the Moon. It lies just to the west of the crater Mitra, and northeast of Raimond.
Dollond is a small lunar impact crater that is located in the central region of the Moon, to the north of the crater Abulfeda. It was named after British optician John Dollond. Due west of Dollond is Anděl. Dollond is circular and cone shaped, with a tiny floor at the midpoint of the sloping interior walls.
Carver is a lunar impact crater that is located on the far side of the Moon, due east of the walled plain Van der Waals. To the northeast is the crater Rosseland, and to the south-southeast lies Kozyrev.
Denning is a lunar impact crater that is located on the far side of the Moon. It lies about midway between the craters Levi-Civita to the south and Marconi to the north-northeast. About two crater diameters to the southeast is the huge walled plain Gagarin.
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.
Fesenkov is a lunar impact crater on the far side of the Moon. It is located to the east-southeast of the prominent crater Tsiolkovskiy, and less than a crater diameter to the north of Stark.
Fleming is a large lunar impact crater that is located on the Moon's far side, and cannot be seen from the Earth. It lies about a crater diameter to the east-northeast of Hertz, and to the northwest of Lobachevskiy.
