Tirawa (Rhea)

Great spirit of Pawnee Tribe (USA), created first men; his messengers were the planets, stars, lightning and thunder.

Tirawa basin is a large impact crater on Saturn's moon Rhea,. It was glimpsed by Voyager 1 during its flyby of the moon and later photographed in greater detail by the Cassini orbiter. Tirawa is 5 kilometers across. The crater has a slightly elliptic outline and an elongated central peak complex suggesting it was caused by an oblique impact. (wikipedia entry)

A crater is a circular depression likely created by an impact event. On Rhea they are named after people and places from creation myths (with Asian emphasis).
