Ctesibius is a small lunar impact crater that is located near the equator, on the far side of the Moon. It is named after the ancient Greek-Egyptian inventor Ctesibius.[1] It lies between the larger crater Abul Wáfa to the west and the slightly smaller Heron to the east.
The outer wall of Ctesibius is wide and sharp-edged, with little erosion. A low ridge is attached to the southern rim, and curves to the south-southeast. At the center of the relatively flat interior is a low ridge. Faint traces of ray material lies across the western floor and rim from Necho to the southeast.
