Divalia Fossae
Trough system on Vesta / From Wikipedia, the free encyclopedia
Divalia Fossae /dɪˈveɪliə ˈfɒseɪ/ is the large series of parallel equatorial troughs on the giant asteroid 4 Vesta. It is one of the longest chasms in the Solar System, stretching across roughly two-thirds of Vesta's equator. The trough system is named after the Roman festival of Divalia; the name Divalia Fossae was officially approved by the International Astronomical Union (IAU) on 27 December 2011.[1]
