Eponym Tui

Tui Regio (located at 20°S, 130°W[1]) is a region on Titan, the Saturnian moon, in the southwest corner of Xanadu,[2] named after Tui, a Chinese goddess of happiness, joy and water.[1] Tui appears to lack the erosion channels that mark other highland regions on Titan, suggesting it may be geologically young.[3] Patterns resembling lava flows have also been observed, suggesting cryovolcanism.[4]
