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.
