Beer is a relatively small lunar impact crater located on the Mare Imbrium, to the east of the crater Timocharis. It was named after German astronomer Wilhelm W. Beer. Just to the northwest is the matching twin Feuillée.
Brayley is a lunar impact crater located in the southwest part of the Mare Imbrium. It was named after British geographer Edward W. Brayley in 1935. It has a circular rim and a low rise in the center. There are no notable craters overlapping the rim or interior. The sinuous rille Rima Brayley passes to the north of Brayley.
Huxley is a tiny lunar impact crater located in eastern inlet of Mare Imbrium, just to the north of the Montes Apenninus. It was named after British biologist Thomas Henry Huxley. To the southeast in this range is Mons Ampère. This crater was previously identified as Wallace B before being renamed by the IAU. The crater Wallace lies due west.
Aratus is a small lunar impact crater located on the highland to the south and east of the rugged Montes Apenninus range. It is a circular, cup-shaped crater with a relatively high albedo. It was named after Greek astronomer Aratus of Soli. To the east is the Mare Serenitatis, and to the southwest is the somewhat larger crater Conon. North-northeast of Aratus is the landing site of the Apollo 15 mission, just beyond Mons Hadley Delta.
Gay-Lussac is a lunar impact crater located to the north of the prominent crater Copernicus, in the southern foothills of the Montes Carpatus range. The rim of the crater is slightly distorted, although generally circular. The inner floor is flat but rough, with no central peak. There are a pair of small craterlet depressions in the middle instead of a central peak. The associated crater Gay-Lussac A is nearly joined to the southeast rim.
Sharp is a lunar impact crater located to the west of the Sinus Iridum bay of the Mare Imbrium, beyond the Montes Jura range. To the southwest is the crater Mairan. Because of its location and foreshortening, Sharp appears elliptical from the earth.
Delisle is a small lunar impact crater in the western part of the Mare Imbrium. It was named after French astronomer Joseph-Nicolas Delisle. It lies to the north of the crater Diophantus, and just to the northwest of the ridge designated Mons Delisle. Between Delisle and Diophantus is a sinuous rille named Rima Diophantus, with a diameter of 150 km. To the northeast is another rille designated Rima Delisle, named after this crater.
Diophantus is a lunar impact crater that lies in the southwestern part of the Mare Imbrium. It was named after ancient Greek mathematician Diophantus. It forms a pair with the larger crater Delisle to the north. Diophantus has a wide inner wall and a low central rise. To the north of Diophantus is the sinuous rille designated Rima Diophantus, named after the crater. Diophantus C lies near the exterior of the southwest wall.
Flammarion is a lunar impact crater on the south edge of Sinus Medii. Its diameter is 76 km. It is named after the French astronomer Camille Flammarion. It is located between the crater Mösting to the northwest and Herschel to the southeast. The bowl-shaped Mösting A intersects the western rim of Flammarion.
Oppolzer is the remnant of a lunar impact crater that is located on the southern edge of Sinus Medii, along the meridian of the Moon. Its diameter is 41 km. It was named after the Austrian astronomer Theodor von Oppolzer. It is located within one crater diameter of the origin of the selenographic coordinate system at 0° N, 0° W. Attached to the surviving remnants of the southeast rim is the crater Réaumur. To the west-southwest is the lava-flooded walled plain Flammarion.
Conon is a small but prominent lunar impact crater that lies in the eastern foothills of the Montes Apenninus mountain range. The crater is named for the Greek astronomer Conon of Samos. Just to the west of Conon is the long mountainous ridge Mons Bradley. The nearest craters possessing an eponym are Galen, about 70 kilometres (43 mi) to the east, and Aratus, about the same distance to the northeast.
Cayley is a small lunar impact crater that is located in a lava-flooded region to the west of Mare Tranquillitatis. It was named after the 19th-century English mathematician Arthur Cayley. It lies to the northwest of the smaller crater De Morgan and the larger D'Arrest. West and slightly north of Cayley is Whewell, a crater of about the same dimensions. To the north is a linear rille designated Rima Ariadaeus, which follows a course to the east-southeast.
Montes Alpes is a mountain range in the northern part of the Moon's near side. It was named after the Alps in Europe; the name was confirmed by the International Astronomical Union in 1935. It lies between the selenographic coordinates latitudes 52.81°N and 42.04°N, and longitudes 5.6°W and 3.22°E. The range thus crosses the lunar prime meridian, and is partially illuminated and partially in shadow during first and last quarters. The center of the range is at 48.36°N, 0.58°W, and has a diameter of 334 km.
Santos-Dumont is a small lunar impact crater that lies in the northern end of the Montes Apenninus range at the eastern edge of the Mare Imbrium. It is located about 30 kilometers to the northeast of Mons Hadley, a mountain massif.
Yangelʹ is a small lunar impact crater that is located in the irregular terrain to the north of the Mare Vaporum. Its diameter is 8 km. It was named after Soviet rocketry scientist Mikhail Kuzmich Yangelʹ in 1973. This crater was formerly designated Manilius F.
Mons Hadley is a massif in the northern portion of the Montes Apenninus, a range in the northern hemisphere of the Moon. It has a height of 4.5 km (2.8 mi) 14,764 ft (4,500 m) above the adjacent plain and a maximum diameter of 25 km at the base.
Mons La Hire is a solitary lunar mountain in the western Mare Imbrium. It is located to the northeast of the crater Euler, and to the west-northwest of Lambert.
Mons Vinogradov is a rugged massif that is located on the lunar mare where Oceanus Procellarum to the southwest joins Mare Imbrium to the east. There are three primary peaks in this formation, which rise to altitudes of 1.0–1.4 km above the surface. To the east of this rise is the crater Euler, and to the southeast is an area of rugged ground that reaches the Montes Carpatus range. The Carpatus mountain range forms the southwest boundary of the Mare Imbrium.
Mons Hadley Delta (δ) is a massif in the northern portion of the Montes Apenninus, a range in the northern hemisphere of the Moon adjacent to Mare Imbrium. It has a height of 3.6 km above the plains to the north and west.
