Veneneia (/vɛnᵻˈniːə/ ven-i-NEE-ə) is the second-largest crater on asteroid 4 Vesta, at 52°S latitude. Lua error in Module:Convert at line 272: attempt to index local 'cat' (a nil value).[1] in diameter, it is 70% of the equatorial diameter of the asteroid, and one of the largest craters in the Solar System. It is at least 2 billion years old.[2] However, it is overlain and partially obliterated by the even larger Rheasilvia. It was discovered by the Dawn spacecraft in 2011. It is named after Venēneia, one of the founding vestal virgins.[3]
Vesta has a series of troughs in the northern hemisphere concentric to Veneneia. These are believed to be large-scale fractures resulting from the impact. The largest is Saturnalia Fossa, approx. 39 km wide and > 400 km long.[4]
