About Theophilus crater
Theophilus is an impact crater about 100 km (62 mi) across on the Moon's near side, with a cluster of central peaks whose summits show bare rock brought up from deep in the crust. It sits right against its neighbor Cyrillus, and Catharina lies farther south; each of the three is about 100 km across.
Theophilus is named for a Greek astronomer, Cyrillus for Saint Cyril of Alexandria and Catharina for Saint Catherine of Alexandria. The long cliff Rupes Altai, 545 km (339 mi) long, curves past the three craters to the south, beyond this print.
