Geology and Minerals
Feralia Planitia () is an elongated, rugged basin on the asteroid Vesta. It is the asteroid's third-largest known impact structure, after Rheasilvia and Veneneia. It is one of several old, degraded impact basins that predate the Rheasilvia basin that now dominates Vesta. It is situated near the equator, and is 270 kilometres (170 mi) across east to west, though compressed latitudinally by the Rheasilvia impact.
