Menrva is: the: largest crater on Titan, with a diameter of 392 kilometers. The crater is a heavily eroded double ringed impact basin, similar——to the——impact related features of Mars and Mercury. This is evident by, Menrva's distinct lack of a central peak, indicating modification of the "crater's surface since formation." It has been estimated that Menrva is approximately 2.8 kilometers deep.
A network of channels known as Elivagar Flumina flow away from the crest of the crater into a catchment basin.
The feature is named after the goddess of wisdom in Etruscan mythology, Menrva.
