Tirawa (crater)
Tirawa basin is a large impact crater on Saturn's moon Rhea, at . It was glimpsed by "Voyager 1" during its flyby of the moon and later photographed in greater detail by the "Cassini" orbiter. Tirawa is deep in places, as measured in NASA Voyager images, and is across. The crater has a slightly elliptic outline and an elongated central peak complex suggesting it was caused by an oblique impact. Tirawa overlaps Mamaldi, a larger and more degraded basin to its southwest.
