Saturnalia Fossa

Saturnalia Fossa runs obliquely near the terminator at upper right of this full view of Vesta, with nearby grooves parallel to it.

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 wide and is at least 365 km long; 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]
