Geber is a lunarimpact crater that is located in the rugged south-central highlands of the Moon. It lies half way 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.Autostar Suite Astronomer Edition. CD-ROM. Meade, April 2006.
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 mid-point. The small satellite crater Geber B is attached to the northwest rim.
It was named after the Spanish-Arab astronomer Geber.
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Geber.
