Menrva is the largest crater on Titan, with a diameter of 392 kilometers.[1] The crater is a heavily eroded double ringed impact basin, similar to the impact related features of Mars and Mercury.[2] This is evident by Menrva's distinct lack of a central peak, indicating modification of the crater's surface since formation.[3] 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.[4]

The feature is named after the goddess of wisdom in Etruscan mythology, Menrva.[1]
