Eponym | Geber |
Geber is a lunar impact crater that is located in the rugged south-central highlands of the Moon. It lies halfway between the crater Almanon to the north-northeast and the crater pair of Azophi and Abenezra to the south-southwest. Farther to the southeast is Sacrobosco. Geber is 45 kilometers in diameter and 3,510 meters deep. [1]
The rim of Geber is symmetrical and nearly circular, with only minor indentations at the north and south faces of its high, terraced wall. The floor is flat and lacks a significant central peak at the midpoint. The small satellite crater Geber B is attached to the northwest rim. [2] [3] Geber is from the Nectarian period. [4]
In 1935, the crater was officially named after Jabir ibn Aflah (Latinized as Geber), a Spanish-Arab astronomer active in the first half of the twelfth century. [5]
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Geber. [6]

Fermat is a lunar impact crater located to the west of the Rupes Altai escarpment. To the west-southwest is the larger crater Sacrobosco, and to the southwest is the irregular Pons. It is 39 kilometers in diameter and two kilometers deep.
Fabricius is a lunar impact crater that is located within the northeast part of the walled plain Janssen. Attached to the north-northwest rim is the slightly larger crater Metius. Fabricius has multiple central peaks that rise to 0.8 km, with a rugged rise to the northwest running north–south. The rim is lumpy and somewhat distended, most noticeably to the southwest and south. It is 78 kilometers in diameter and 2,500 meters deep. It is from the Eratosthenian period, 3.2 to 1.1 billion years ago. It is named after David Fabricius, a 16th-century German astronomer.
Eddington is the lava-flooded remnant of a lunar impact crater, located on the western part of Oceanus Procellarum. The western rim is attached to the wall of the walled plain Struve. To the east-southeast is the smaller but prominent crater Seleucus. South of Eddington is Krafft.
Argelander is a lunar impact crater that is located in the south-central highlands of the Moon. It was named after the German astronomer Friedrich Argelander. It lies in the midpoint between the smaller crater Vogel in the north and the larger Airy to the south. To the northwest is the worn remnant of Parrot. Just to the west is a shallow cleft in the surface that follows a course to the north-northwest, intersecting the southeast rim of Parrot.
Cleomedes is a prominent lunar impact crater located in the northeast part of the visible Moon, to the north of Mare Crisium. It was named after Greek astronomer Cleomedes. It is surrounded by rough ground with multiple crater impacts. The irregular crater Tralles intrudes into the northwest rim. To the east is Delmotte. North of Cleomedes is a triple-crater formation with Burckhardt occupying the center.
Abenezra is a lunar impact crater located in the rugged highlands in the south-central section of the Moon. Abenezra is named after the Sephardic Jewish sage, poet, biblical commentator, astronomer, and astrologer Abraham ibn Ezra. It is attached along the southeast rim to the crater Azophi. To the northeast lies the crater Geber, and further to the southeast is the larger Sacrobosco.
Agrippa is a lunar impact crater that is located at the southeast edge of the Mare Vaporum. It is located to the north of the crater Godin, the irregular Tempel lies just to the east. To the north and northeast, the rille designated Rima Ariadaeus follows a course to the east-southeast, reaching the western edge of Mare Tranquillitatis. It is named after the 1st century Greek astronomer Agrippa. Its diameter is 44 km (27 mi).
Aliacensis is a lunar impact crater that is located in the rugged southern highlands of the Moon. The crater Werner is located just to its north-northwest, and a narrow, rugged valley lies between the two comparably sized formations. To the southwest is Walther, and Apianus is to the northeast. Aliacensis is named after the 14th century French geographer and theologian Pierre d'Ailly. It is from the Nectarian period, which lasted from 3.92 to 3.85 billion years ago.
Almanon is a lunar impact crater that lies in the rugged highlands in the south-central region of the Moon. It was named after Abbasid Caliph and astronomer Al-Ma'mun. It is located to the south-southeast of Abulfeda, and to the north-northeast of the smaller crater Geber. The crater chain designated Catena Abulfeda forms a line between the south rim of Abulfeda and the north rim of Almanon, continuing for a length of about 210 kilometers to the Rupes Altai scarp.
Anděl is a lunar impact crater that lies in the rugged central highlands of the Moon. It was named after the Czech astronomer Karel Anděl. Nearby craters of note include Abulfeda to the south-southeast and Descartes to the east-southeast. About 85 kilometres to the east-northeast of the outer rim is the landing site of the Apollo 16 mission.
Apianus is a lunar impact crater that is located on the rugged south-central highlands of the Moon. It is named after 16th century German mathematician and astronomer Petrus Apianus. It is located to the northeast of the crater Aliacensis, and to the northwest of Poisson. The worn crater Krusenstern is attached to the west-northwestern rim.
Boss is a lunar impact crater that is located along the northeast rim of the Moon's near side. Due to its location, the crater is viewed from the side by observers on the Earth, and its visibility is subject to libration effects.
Baco is a lunar impact crater that lies in the rugged southern highlands on the near side of the Moon. The rim and inner wall has been eroded and worn by countless minor impacts since the original formation of the crater. As a result, any terraces have been worn smooth and the rim is overlaid by several tiny craterlets. The interior floor is nearly flat, with no characteristic central peak at the midpoint and no small craters of significance.
Donati is a lunar impact crater that is located in the rugged south-central highlands of the Moon. It lies just to the northwest of the crater Faye, and the two outer rims are separated by a gap of less than 10 kilometers. To the north is the comparably sized Airy, and farther to the southeast is Playfair. Donati is 36 kilometers in diameter.
Blanchinus is a lunar impact crater that is situated in the rugged south-central highlands of the Moon. The crater is named after Italian astronomer Giovanni Bianchini whose Latinized name is Blanchinus. Adjacent to the south of Blanchinus is the crater Werner, and La Caille is attached to the northwest rim. West of the crater is the prominent formation Purbach.
Borda is a lunar impact crater that lies between Santbech to the north-northwest and Reichenbach slightly further away to the south-southeast. It was named after French astronomer Jean-Charles de Borda. It has a low rim that is broken along the southeast by a smaller crater. The rim is intruded into by another small crater along the southwest side, and there is an irregular cleft along the northwest face. There is a central peak at the midpoint of the floor.
Banachiewicz is a largely degraded lunar impact crater that is located near the eastern limb of the Moon.
Chrétien is a lunar impact crater that is located in the southern hemisphere on the far side of the Moon from the Earth. It lies due south of the Mare Ingenii, one of the few maria on the Moon's far side. The crater lies in the midpoint between the craters Garavito to the west-southwest and Oresme to the east-northeast, both of these being somewhat smaller than Chrétien.
Dreyer is the remnant of a lunar impact crater on the far side of the Moon. It is located along the eastern edge of the Mare Marginis, about midway between the craters Ginzel to the north and Erro to the south-southeast. It was named after Danish-Irish astronomer John L. E. Dreyer.
Evershed is a lunar impact crater on the far side of the Moon, named after the English solar astronomer John Evershed. It is located to the northeast of the larger crater Cockcroft, and to the north of the smaller Van den Bergh.
