Geber (crater)
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]
Satellite craters
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]
