Menrva is the largest confirmed impact crater on Saturn’s moon Titan.
Menrva is a huge, heavily eroded, double-ringed impact basin measuring about 392 kilometers across. Its broad, subdued form indicates that Titan’s surface has modified the original crater through geological processes, including erosion, deposition and possible flow of surface materials. Menrva is estimated to be approximately 2.8 kilometers deep and lacks the prominent central peak found in many fresher impact craters.
The feature was identified in radar and imaging data returned by NASA’s Cassini spacecraft during its exploration of Titan. Channels called Elivagar Flumina appear to flow away from Menrva’s raised rim into a surrounding catchment area, linking the crater to Titan’s active surface landscape.
The name Menrva comes from Etruscan mythology, where Menrva was a goddess of wisdom. The other options are craters on different worlds or moons: Evander is on Dione, Odysseus is on Tethys, and Herschel is on Mimas.
