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.
Fracastorius is the lava-flooded remnant of an ancient lunar impact crater located at the southern edge of Mare Nectaris. To the northwest of this formation lies the crater Beaumont, while to the northeast is Rosse.
Armstrong is a small lunar impact crater located in the southern part of the Mare Tranquillitatis. It lies about 50 kilometers to the northeast of the Apollo 11 landing site, Tranquility Base. Named after American astronaut Neil Armstrong, the crater is the easternmost of the row of three craters named in honor of the Apollo 11 crew members. To the north is the Ranger 8 impact site.
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.
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.
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.
Al-Bakri is a small lunar impact crater on the northwest edge of Mare Tranquillitatis. It is named after the Spanish Arab geographer and historian Abu Abdullah al-Bakri. It is just south of the eastern arm of the Montes Haemus that borders the Mare Serenitatis to the north. To the east-northeast is the prominent crater Plinius. South of the crater are the rilles of the Rimae Maclear.
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.
Euler is a lunar impact crater located in the southern half of the Mare Imbrium, and is named after the Swiss mathematician, physician and astronomer Leonhard Euler. The most notable nearby feature is Mons Vinogradov to the west-southwest. There is a cluster of low ridges to the southwest, and this formation includes the small crater Natasha and the tiny Jehan. About 200 kilometers to the east-northeast is the comparably sized crater Lambert.
Fauth is a small double-crater located at the edge of the rough southern ramparts of the prominent ray crater Copernicus on the Moon. It lies in the Mare Insularum, to the northeast of the crater Reinhold. The crater is named after German selenographer Philipp Johann Heinrich Fauth.
Bonpland is the remains of a lunar impact crater that is attached to the walled plain Fra Mauro to the north and Parry to the east. The intersection of their rims forms a three-pointed mountainous rise. To the southeast is the small crater Tolansky. Bonpland lies on the eastern edge of Mare Cognitum. It is named after Aimé Bonpland, a French explorer and botanist.
Guericke is the remnant of a lunar impact crater at the north part of the Mare Nubium. It is named after German scientist Otto von Guericke. To the north-northwest lies the large Fra Mauro crater, along with the co-joined craters Parry and Bonpland. To the east are the craters Kundt and Davy.
Parry is a lunar impact crater that is attached to the southeast rim of the walled plain Fra Mauro. It was named after British explorer William Parry. Attached to the west and southwest rim of Parry is the crater Bonpland. Due south of Parry is the small crater Tolansky, and farther to the south-southwest is Guericke.
Tolansky is a small, circular lunar impact crater that is located due south of the crater Parry on the Mare Cognitum. The formation is symmetric, with a light-hued outer rim and a darker interior floor. A rille belonging to the Rimae Parry almost connects with the north-northwestern rim of Tolansky.
D'Arrest is a lunar impact crater that is located in the lava-flooded region to the west of the Mare Tranquillitatis. It is named after the German astronomer Heinrich Louis d'Arrest. It lies to the southeast of the crater Agrippa and northwest of Delambre. Just to the northeast are the small, bowl-shaped craters De Morgan and Cayley.
Bouguer is a lunar impact crater that lies along the southern edge of the Mare Frigoris, to the north of the crater Bianchini. To the west-southwest of Bouguer, along the same shore of the mare, is the crater Foucault. Nearly due west is the more prominent Harpalus, and to the west is La Condamine.
Blackett is a lunar impact crater that lies on the far side of the Moon, behind the southwest limb. It lies beyond the southeast outer ring of the immense Mare Orientale basin. The formation of that major feature has left Blackett deeply marked with ridge features trending from the northwest. Much of the crater has been shaped by the ejecta from Mare Orientale, particularly along the western half of the crater.
Fabbroni is a small lunar impact crater that lies along the northern edge of the Mare Tranquillitatis, at the eastern edge of the gap where the lunar mare joins Mare Serenitatis to the north. To the southeast is the crater Vitruvius.
Dunthorne is a small lunar impact crater that is located to the northwest of the small lunar mare called Palus Epidemiarum, in the southwest part of the Moon's near side. It was named after British astronomer Richard Dunthorne. It lies to the southwest of the crater Campanus, east of Vitello. Due south is Ramsden.
Daubrée is a lunar impact crater that is located to the southwest of the Mare Serenitatis, just to the west-southwest of the crater Menelaus in the Montes Haemus range. The small lunar mare Lacus Hiemalis lies along the southwest rim of Daubrée. The crater was named after French geologist Gabriel A. Daubrée. It was previously designated Menelaus S.
