Fra Mauro is the worn remnant of a walled lunar plain. It is part of the surrounding Fra Mauro formation, being located to the northeast of Mare Cognitum and southeast of Mare Insularum. Attached to the southern rim are the co-joined craters Bonpland and Parry, which intrude into the formation forming inward-bulging walls. The crater is named after Italian geographer Fra Mauro.
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.
Dawes is a lunar impact crater located in the wide straight between Mare Serenitatis and Mare Tranquilitatis. To its southwest lies the larger crater Plinius, and to its northeast sits the Mons Argaeus mountain rise. It is named after British astronomer William Rutter Dawes.
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.
Jansen is a lunar impact crater in the north part of the Mare Tranquillitatis. The diameter is 24 km. It was named after 17th century Dutch optician Zacharias Janssen. It is located to the east-southeast of the crater Plinius. The rim of Jansen is low and narrow, with a notch along the western edge. The interior is relatively level, which may indicate it has been covered by lava. To the south-southwest a small but prominent crater lies on the crater floor, halfway between the center and the rim.
Apollonius is a lunar impact crater located near the eastern limb of the Moon. It lies in the region of uplands to the west of Mare Undarum and northeast of the Sinus Successus on the Mare Fecunditatis. It was named after Greek mathematician Apollonius of Perga. It is southwest of the crater Firmicus, and north of Condon.
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.
Lansberg is a lunar impact crater on the Mare Insularum. It can be located by following a line south-southwest from Copernicus to Reinhold, then southwest to Lansberg. The crater has a high rim and a central mountain. There are terraces along the inner walls, and the tops have slumped to produce a sharp edge. This formation is not noticeably eroded, and there are no significant impact craters within the interior.
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.
Sinas is a small lunar impact crater that lies in the eastern part of the Moon on the Mare Tranquillitatis. Its diameter is 12 km. It was named after the Greek magnate Simon Sinas. This is an isolated formation that is located very near the midpoint of the lunar mare. Sinas is circular and bowl-shaped, with a small floor at the midpoint. A wrinkle ridge intersects the east edge of the crater, and several lunar domes lie to the north.
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 petite means small in French. But it was actually named in honor of Alexis Thérèse Petit, a French physicist.
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.
Chauvenet is a lunar impact crater that is located to the northeast of the prominent crater Tsiolkovskiy on the far side of the Moon. Less than one crater diameter to the northwest of Chauvenet is the crater Ten Bruggencate.
Eichstadt is a lunar impact crater that is located in the eastern section of the Montes Cordillera range that encircles the Mare Orientale impact basin. It lies toward the southwestern limb of the Moon, and so appears oblong when viewed from the Earth due to foreshortening. Over 200 kilometers to the east of Eichstadt are the craters Darwin and Lamarck, and to the south is Krasnov.
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.
Firsov is a lunar impact crater on the far side of the Moon. It is located to due south of the crater Lobachevskiy, and to the northwest of Abul Wáfa. The circular rim of this crater has a small outward bulge along the southern edge, and smaller bulges along the western side. The inner walls have slumped to form talus piles along the base. The low-albedo interior floor is nearly level and featureless.
Sklodowska (Skłodowska) is a large lunar impact crater that is located on the far side of the Moon. It lies just past the southeastern limb, and can sometimes be viewed from Earth under favorable conditions of libration and illumination. The crater is located to the northeast of the older walled plain Curie, and to the southwest of Pasteur, another walled plain.
Litke is a lunar impact crater that lies within the large walled plain Fermi, near the north-northwestern inner rim. Less than one crater diameter to the west-northwest is the slightly larger Delporte. Litke is located on the far side of the Moon and cannot be viewed directly from the Earth.
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.
Waterman is a lunar impact crater that is located on the Moon's far side, and cannot be viewed directly from the Earth. It lies along the southern outer ramparts of the prominent crater Tsiolkovskiy. Almost attached to the southwest is Neujmin, so that Waterman lies straddled between these two features.
