Ameghino is a lunar impact crater located to the north of the Sinus Successus, a bay in the northeast part of Mare Fecunditatis. Less than 15 kilometers to the northwest of Ameghino were the landing sites of the Soviet Luna 18 and Luna 20 probes.
This formation was designated Apollonius C before being given a name by the IAU, in honour of the Argentine scientific and paleontologist Florentino Ameghino."Ameghino (crater)" . Gazetteer of Planetary Nomenclature. USGS Astrogeology Research Program. Apollonius itself is located to the east-northeast.
Artsimovich is a small lunar impact crater located in the western Mare Imbrium of the Earth's Moon. This is a circular crater forming a cup-shaped excavation in the surface of the lunar mare. It is named after Soviet physicist Lev A. Artsimovich. To the east is the crater Diophantus and to the northeast lies Delisle. Less than 20 kilometers to the north-northeast is the tiny Fedorov. This crater was identified as Diophantus A before being named by the International Astronomical Union.
Fahrenheit is a tiny lunar impact crater located in the southeast part of the Mare Crisium. This area of the surface is nearly devoid of impact features of interest. To the east are the Dorsa Harker wrinkle ridges, and beyond them is Promontorium Agarum at the edge of the mare. The landing site of the Soviet Luna 24 probe is located about 15 kilometers to the southeast.
Deslandres is the heavily worn and distorted remains of a lunar impact crater. It is located to the southeast of the Mare Nubium, in the rugged southern highlands of the Moon. In dimension it is the third-largest crater formation on the visible Moon, being beaten only by Clavius and by the 303-kilometer-diameter walled plain Bailly. The northern and eastern parts of the floor display a relatively level surface, but it is pock-marked with numerous craters. There is a small region of mare material, due to basaltic lava, along the eastern interior floor.
Abbot is a small lunar impact crater that lies on the rugged ground between the Mare Fecunditatis in the south and west, and the Mare Crisium to the north. It is a circular crater with a cup-shaped interior. The inner walls slope downward to the midpoint, and no impacts of significant mark the interior or the rim.
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.
Bombelli is a small lunar impact crater that is located in the highlands to the north of the Sinus Successus. It was named after Italian mathematician Raphael Bombelli. It was previously designated Apollonius T. The crater Apollonius is located to the east-southeast.
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.
Cartan is a small lunar impact crater near the eastern edge of the Moon. It lies just to the west of the larger Apollonius. The rim is circular with a tiny crater along the eastern side. The interior floor is about half the diameter of the crater. A smaller crater attached to the southern rim is also attached to the north rim of Apollonius H, forming a short crater chain.
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.
Cavalerius is a prominent lunar impact crater that lies on the western edge of the Oceanus Procellarum lunar mare on the west part of the visible Moon. It nearly joins the northern rim of Hevelius to the south.
Artamonov is a lunar impact crater that is located on the far side of the Moon. The eroded outer rim of Artamonov does not have the circular shape of most lunar craters, and instead has the overall shape of three or four merged craters. The largest of these formations is in the south, with smaller circular bulges to the north and east.
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.
Petit is a small, bowl-shaped lunar impact crater that is located on the northwestern edge of the Mare Spumans. The crater has a prominent ray system. The name is appropriate, since Petit means small in French. But it was actually named in honor of Alexis Thérèse Petit, a French physicist.
Condon is a lunar impact crater that lies on the eastern shore of the Sinus Successus, a bay along the northeast edge of Mare Fecunditatis. It was named after American physicist Edward U. Condon. It lies midway between the larger crater Apollonius to the north and the smaller Webb to the south on the Mare Fecunditatis. Condon was previously designated Webb R.
Firmicus is a lunar impact crater that lies in the eastern part of the Moon's near side, so that from Earth it appears oval in shape due to foreshortening. It is, however, very nearly circular. The crater is located to the west of the Mare Undarum, and northeast of the similar-sized crater Apollonius. To the north of Firmicus are the craters van Albada and Auzout. Attached to its northwest rim is the Lacus Perseverantiae, a miniature lunar mare.
Damoiseau is a lunar impact crater that is located just to the west of the Oceanus Procellarum, in the western part of the Moon's near side. It lies due east of the prominent crater Grimaldi, a walled plain with a distinctive dark floor. Due south of Damoiseau is the crater Sirsalis.
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.
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.
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.
