Mare Tranquillitatis
Hypatia was honored as an astronomer when 238 Hypatia, a main belt asteroid discovered in 1884, was named for her. The lunar crater "Hypatia" was also named for her, in addition to craters named for her father Theon. The 180 km "Rimae Hypatia" are located north of the crater, one degree south of the equator, along the Mare Tranquillitatis.
