Tui Regio
Tui Regio (located at 20°S, 130°W) is a region on Titan, the Saturnian moon, in the southwest corner of Xanadu, named after Tui, a Chinese goddess of happiness, joy and water.

Patterns resembling lava flows have also been observed, suggesting cryovolcanism.
current system was adopted by the International Astronomical Union, the body which oversees planetary nomenclature.
The longitudes of physical features on Venus are expressed relative to its prime meridian. The original prime meridian passed through the radar-bright spot at the centre of the oval feature Eve, located south of Alpha Regio. After the Venera missions were completed, the prime meridian was redefined to pass through the central peak in the crater Ariadne.
