Saturnalia_Fossa Knowpia

Saturnalia Fossa /sætərˈneɪliə ˈfɒsə/ is the largest of the series of parallel Veneneian troughs in the northern hemisphere of the giant asteroid 4 Vesta. It is estimated to be approx. 39 km (24 mi) wide and is at least 365 km (227 mi); as of early 2012, one end disappeared in shadow and its total length was thus unknown. It is thought to be a shock fractures resulting from the impact that created Veneneia crater, which it is concentric with.^[1] It is one of the longer chasms in the Solar System, and is named after the Roman festival of Saturnalia.^[2]
