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.
Sirsalis is a relatively young lunar impact crater located near the western lunar limb, to the southwest of the Oceanus Procellarum. The crater lies across a ridge that runs in a north–south direction. It has a sharp edge and a low central peak. The crater overlaps the slightly larger and older Sirsalis A to the west-southwest, and the two form a distinctive feature.
Triesnecker is a prominent lunar impact crater that is located in the Sinus Medii, near the central part of the Moon's near side. Its diameter is 25 km. It was named after Austrian astronomer Franz de Paula Triesnecker. It is located to the north-northwest of the crater Rhaeticus, and to the east-southeast of the flooded Murchison.
Ariadaeus is a small, bowl-shaped lunar impact crater on the western shores of Mare Tranquillitatis. It lies to the north of the crater Dionysius, and to the west-southwest of Arago. The crater is joined along the northeast rim by the slightly smaller Ariadaeus A, and the two form a double-crater. Its diameter is 10.4 km.
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.
Boscovich is a lunar impact crater that has been almost completely eroded away by subsequent impacts. It is located west-northwest of the crater Julius Caesar, and south-southeast of the prominent Manilius. The crater floor has a low albedo, and the dark hue makes it relatively easy to recognize. The surface is crossed by the rille system designated Rimae Boscovich that extends for a diameter of 40 kilometres. The crater is named after Croatian physicist Roger Joseph Boscovich.
Cavendish is a lunar impact crater that is located in the southwest part of the Moon, to the southwest of the larger crater Mersenius. It lies between the smaller craters Henry to the west-northwest and de Gasparis to the east-southeast.
Goclenius is a lunar impact crater that is located near the west edge of Mare Fecunditatis. It lies to the southeast of the lava-flooded crater Gutenberg, and north of Magelhaens. To the northwest is a parallel rille system that follow a course toward the northwest, running for a length of up to 240 kilometers. This feature is named the Rimae Goclenius.
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.
Hippalus is the remnant of a lunar impact crater on the eastern edge of Mare Humorum. It was named after ancient Greek explorer Hippalus. To the southeast is the crater Campanus, and to the northwest is the small flooded crater Loewy.
Sosigenes is a lunar impact crater on the west edge of Mare Tranquillitatis. Its diameter is 17 km. It was named after ancient Greek astronomer Sosigenes of Alexandria. It lies to the east of the large walled plain Julius Caesar. The crater rim has a high albedo, making it relatively bright. It has a small central rise at the midpoint of the floor.
De Vico is a small lunar impact crater that is located in the southwest part of the Moon, to the south of the crater Sirsalis. To the west-northwest is Crüger. De Vico is a circular, bowl-shaped formation with a small, flat bottom at the midpoint. To the northwest is the lava-flooded remains of De Vico T. Beyond is a linear rille designated Rimae Sirsalis that follows a path to the northeast past the rim of Sirsalis.
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.
Krieger is a lunar impact crater on the eastern part of the Oceanus Procellarum. It is located to the north-northwest of the flooded crater Prinz, and north-northeast of the prominent ray crater Aristarchus. To the northwest lies the small Wollaston.
Campanus is a lunar impact crater that is located on the southwestern edge of Mare Nubium. It was named after Italian astronomer Campanus of Novara. It forms a crater pair with Mercator just to the southeast. Along the southern rampart of Campanus is the small lunar mare named Palus Epidemiarum. To the southwest is the small crater Dunthorne.
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.
Maclear is a lava-flooded crater on the northwest part of the Mare Tranquillitatis, a lunar mare in the eastern half of the Moon. Its diameter is 20 km. The crater is located to the southwest of the slightly larger Ross. To the southwest of Maclear is Sosigenes, while farther to the south-southeast is Arago.
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.
Galvani is a lunar impact crater that lies close to the northwestern limb of the Moon, due south of the larger walled plain Volta. It partly overlies the southeast rim of the crater Langley, which occupies half the gap between Volta and Galvani. To the northeast is the large walled plain Repsold, and to the west-southwest, on the far side of the Moon, is the crater McLaughlin.
Fontana is a lunar impact crater that is located in the southwestern part of the Moon's near side, to the south of the Oceanus Procellarum. It lies to the west-northwest of the flooded crater Zupus. Midway between Fontana and Zupus is a rille system designated Rimae Zupus.
