Named after Timocharis - Greek astronomer (unkn-fl. c. 280 B.C.).
Timocharis is a prominent lunar impact crater located on the Mare Imbrium. The closest crater of comparable dimensions is Lambert to the west. The smaller craters Feuillée and Beer lie to the east. The rim has a somewhat polygonal outline, with an outer rampart that extends over 20 kilometers in all directions. (wikipedia entry)
