Rheasilvia / ˌ r iː ə ˈ s ɪ l v i ə / is the largest impact crater on the asteroid Vesta. It is 505 km (314 mi) in diameter, which is 90% the diameter of Vesta itself, and is 95% the mean diameter of Vesta, 529 km (329 mi).
The most prominent of these surface features are two enormous impact basins, the 500-kilometre (311 mi)-wide Rheasilvia, centered near the south pole; and the 400 km (249 mi) wide Veneneia. The Rheasilvia impact basin is younger and overlies the Veneneia. [75] The Dawn science team named the younger, more prominent crater Rheasilvia, after the ...
