Aepinus is a small lunar impact crater located along the northern lunar limb, close to the north pole of the Moon. To the south east is the prominent crater Hermite.
This crater was unnamed until it was given a name along with 18 other craters by the IAU on January 22, 2009. It was named after the German-Russian astronomer Franz Aepinus (c. 1724 – c. 1802).
Al-Marrakushi is a small, relatively isolated lunar impact crater in the eastern Mare Fecunditatis. It is a circular, symmetrical formation, with inner walls that slope down to the midpoint. To the northeast is the prominent crater Langrenus. The mare near Al-Marrakushi is marked by ray material from its larger neighbor.
Daguerre is a circular formation near the north end of Mare Nectaris. To the west-northwest is the crater Mädler, and beyond it to the west is the prominent Theophilus. To the north in the rugged continental area between the maria is Isidorus.
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.
Anville is a relatively small, solitary lunar impact crater located in the north part of the Mare Fecunditatis. It is named after French cartographer Jean-Baptiste d'Anville. This is a circular, cup-shaped formation with a sharp edge and little appearance of wear. Some minor slumping has occurred in the eastern half of the interior wall. It was designated Taruntius G prior to being assigned a name by the IAU. Taruntius itself lies to the north-northwest, at the edge of the mare.
Beketov is a small lunar impact crater that lies in the northern reaches of the Mare Tranquillitatis. It is named after Russian chemist Nikolay Beketov. To the south is the ghost crater Jansen R. Northeast of Beketov, along the edge of the mare, is the crater Vitruvius. Beketov was previously designated Jansen C before being named by the IAU. The flooded crater Jansen itself lies to the south.
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.
Curtis is a very small lunar impact crater that lies in the western Mare Crisium, to the east of the crater Picard. It is a circular, cup-shaped formation that is otherwise undistinguished. It was named after American astronomer Heber D. Curtis in 1973. In the past it was designated Picard Z.
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.
Atwood is a small earth moon impact crater that is located on the Mare Fecunditatis, to the northwest of the prominent crater Langrenus. It forms a triple-crater formation with Naonobu attached to the north rim and Bilharz near the west rim.
Back is a small lunar impact crater that is located near the eastern limb of the Moon. It lies on the northwest edge of the Mare Smythii, and the northeast rim is adjacent to the crater Schubert. To the west is Jenkins, and to the southwest is the Weierstrass–Van Vleck crater pair.
Barkla is a lunar impact crater that lies near the eastern limb of the Moon. It is located to the east of the prominent crater Langrenus, and was formerly designated Langrenus A before being renamed by the IAU in 1979. Due east of Barkla is Kapteyn, a formation only slightly larger with a similar size. Southwest of Barkla is the crater Lamé.
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.
Eckert is a tiny, isolated lunar impact crater in the northern part of the Mare Crisium. This crater forms a circular pit in the dark surface of the surrounding lunar mare. Just to the west is a wrinkle ridge in the mare surface, a feature that is prominent only under oblique lighting from the Sun. The nearest craters of note are Peirce to the west-northwest, and Picard to the southwest. Both of these craters lie in the Mare Crisium basin.
Bondarenko is a lunar impact crater on the far side of the Moon. It is located to the northeast of the large, dark-floored crater Tsiolkovskiy, and south of the crater Chauvenet. This is a worn crater formation with an irregular floor, similar to other craters in the area, which are covered by ejecta from Tsiolkovskiy.
Chalonge is a lunar impact crater that is located on the far side of the Moon. It lies to the southwest of the larger crater Lewis, in the outer skirt of ejecta that surrounds the Mare Orientale impact basin. To the southeast are the Montes Cordillera, a ring of mountains that encircle the Mare Orientale formation.
Debus is a small lunar impact crater that is located on the far side of the Moon, past the eastern limb. It lies to the east-southeast of the crater Ganskiy, and just to the west of the huge walled plain Pasteur.
Florensky is a lunar impact crater that is attached to the northeastern rim of the larger crater Vernadskiy. It is located on the far side of the Moon and cannot be directly seen from the Earth. The rim of this crater has been heavily eroded and it forms an irregular ring about the uneven interior. This crater was previously identified as Vernadskiy B before being assigned a name by the IAU in 1985.
Fibiger is a lunar impact crater located on the lunar near side near the northern pole. The nearest major feature is the Byrd crater. The crater was adopted and named after Danish pathologist Johannes Andreas Grib Fibiger in 2009 by the IAU. Located just north of Fibiger are craters Erlanger and Peary, which are 9.9 km and 73 km in diameter, respectively.
Florey is a lunar impact crater on the lunar near side near the northern pole. Florey is directly adjacent to Byrd crater to the Southeast and Peary crater to the North. The crater is named after Australian scientist Howard Florey. The crater was named by the IAU in 2009.
