Wichmann is a bowl-shaped lunar impact crater. It was named after German astronomer Moritz L. G. Wichmann. It is located in the southern half of Oceanus Procellarum on a low plateau formed from a wrinkle ridge, Dorsa Ewing.
Archimedes is a large lunar impact crater on the eastern edges of the Mare Imbrium. Its diameter is 81 km.
Messier is a relatively young lunar impact crater located on the Mare Fecunditatis. The crater has a discernible oblong shape that is not caused by foreshortening. The longer dimension is oriented in an east–west direction.
Collins is a tiny lunar impact crater located on the southern part of the Mare Tranquillitatis. It is located about 25 kilometers to the north of the Apollo 11 landing site, Tranquility Base. Named after American astronaut Michael Collins, the crater is the central member of the row of three craters named in honor of the Apollo 11 crew members. About 15 kilometers to the west-northwest is the landing site of the Surveyor 5 lunar probe.
Euclides is a small lunar impact crater located near the eastern edge of Oceanus Procellarum, about 30 kilometers to the west of the Montes Riphaeus mountains. The mare in the vicinity is devoid of significant craters, but to the west is an area of low rises. The crater is named after the Greek mathematician Euclid.
Balmer is the lava-flooded remains of a lunar impact crater. Only the heavily worn southern and eastern sections of the crater still survive; the remainder being overlaid by a lava flow that joins to the nearby mare. Balmer lies to the east-southeast of the crater Vendelinus.
Hyginus is a lunar caldera located at the east end of the Sinus Medii. It was named after ancient Roman astronomer Gaius Julius Hyginus. Its rim is split by a 220 kilometer-long rille, Rima Hyginus, that branches to the northwest and to the east-southeast. The crater is deeper than the rille, and lies at intersection of the rille's branches. Together, the crater and the rille form a prominent feature in an otherwise flat surface. Smaller craters along the length of the rille may have been caused by the collapse of an underlying structure.
Burnham is a small crater located to the southeast of the crater Albategnius, in a relatively smooth area of the lunar surface. It was named after American astronomer Sherburne W. Burnham. To the southwest is Vogel.
Proclus is a young lunar impact crater located to the west of the Mare Crisium, on the east shore of the Palus Somni. Its diameter is 27 km. It was named after 5th century Greek mathematician, astronomer and philosopher Proclus.
Maskelyne is a solitary lunar impact crater that lies in the southeast part of the Mare Tranquillitatis. Its diameter is 22 km. It was named after British astronomer Nevil Maskelyne. The outer rim has a somewhat polygonal shape, although it is generally circular. The inner walls are terraced and there is a low central rise at the midpoint of the floor.
Secchi is a small lunar impact crater formation on the northwest edge of Mare Fecunditatis. It was named after the 19th-century Italian astronomer Angelo Secchi. To the northeast is the crater Taruntius. The western rim is joined with a section of the minor Montes Secchi range. The rim of this crater has been opened in the northern and southern ends, leaving two curved ridges facing each other across the crater floor. To the south is a pair of rilles designated the Rimae Secchi. These lie near the edge of the mare, and have a combined length of about 40 kilometers.
Tsiolkovskiy is a large lunar impact crater that is located on the far side of the Moon. Named for Russian scientist Konstantin Tsiolkovsky, it lies in the southern hemisphere, to the west of the large crater Gagarin, and northwest of Milne. Just to the south is Waterman, with Neujmin to the south-southwest. The crater protrudes into the neighbouring Fermi, an older crater of comparable size that does not have a lava-flooded floor.
Vesalius is a lunar impact crater that lies on the far side of the Moon, less than 100 kilometers south of the lunar equator. It was named after Flemish anatomist and physician Andreas Vesalius. Just to the northwest is the slightly smaller crater Buisson. Farther to the west-southwest lies the prominent crater Einthoven.
Banachiewicz is a largely degraded lunar impact crater that is located near the eastern limb of the Moon.
Dobrovolʹskiy is a small lunar impact crater on the Moon's far side. The northwest part of its rim is intruded upon by the somewhat larger crater Shirakatsi, and the outer rampart of that feature covers most of the interior floor of Dobrovolʹskiy. Very little of the original floor now survives, with a small section near the southern inner wall. The remainder of the crater rim is somewhat circular and only mildly worn.
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.
Recht is a small impact crater on the far side of the Moon. It was named after the American mathematician and astronomer Albert William Recht. Is lies across the eastern rim of the much larger crater Ostwald. To the northeast of Recht is Meshcherskiy.
Konstantinov is a lunar impact crater that is located to the southeast of the Mare Moscoviense, on the far side of the Moon. To the west of Konstantinov is the smaller crater Nagaoka, and to the south-southeast is the small Van Gent.
Shirakatsi is an impact crater that is located on the Moon's far side. It is attached to the southern exterior rim of the larger crater Perepelkin, and overlies the northwestern rim of Dobrovol'skiy.
Lobachevskiy is a lunar impact crater that is located on the far side of the Moon, beyond the eastern limb. It was named after Russian mathematician Nikolai Lobachevsky in 1961. This crater lies to the southeast of the larger crater Fleming. Less than a crater diameter to the east-northeast lies Guyot.
