Veneneia is the second-largest impact crater on the asteroid Vesta, at 52°S latitude. 'Vesta seems more planet than asteroid' , Science News, 2012 Mar 22 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, and possibly as old as 4.2 billion years. 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.Veneneia, Gazetteer of Planetary Nomenclature, 2012 Feb 28 (NASA coordinates)
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 Fossae, around 39 km wide and > 400 km long.
