Divalia Fossa
Divalia Fossa /dɪˈveɪliə ˈfɒsə/ is the largest of the series of parallel Rheasilvian equatorial troughs on the giant asteroid 4 Vesta. It is approximately 10 km (6.2 mi) wide (estimated 22 km (14 mi) at its widest point) and encircles "most" of Vesta's equator,[1] or for at least 465 km (289 mi), and is about 5 km (3.1 mi) deep. It is thought to be a compression fracture resulting from the impact that created Rheasilvia crater. It is one of the longer chasms in the Solar System, and is named after the Roman festival of Divalia.[2]
