Editing 4 Vesta (section)

===Troughs===
The majority of the equatorial region of Vesta is sculpted by a series of parallel troughs designated [[Divalia Fossae]]; its longest trough is {{convert|10|–|20|km}} wide and {{convert|465|km}} long. Despite the fact that Vesta is a one-seventh the size of the Moon, Divalia Fossae dwarfs the [[Grand Canyon]]. A second series, inclined to the equator, is found further north. This northern trough system is named [[Saturnalia Fossae]], with its largest trough being roughly 40&nbsp;km wide and over 370&nbsp;km long. These troughs are thought to be large-scale [[graben]] resulting from the impacts that created Rheasilvia and Veneneia craters, respectively. They are some of the [[List of largest rifts and valleys in the Solar System|longest chasms in the Solar System]], nearly as long as [[Ithaca Chasma]] on [[Tethys (moon)|Tethys]]. The troughs may be graben that formed after another asteroid collided with Vesta, a process that can happen only in a body that is differentiated,<ref name="Buczkowski2012"/> which Vesta may not fully be. Alternatively, it is proposed that the troughs may be radial sculptures created by secondary cratering from Rheasilvia.<ref name = "Hirata et al. 2023">{{cite journal |url=https://doi.org/10.1029/2022JE007473 |title=Secondary Cratering From Rheasilvia as the Possible Origin of Vesta's Equatorial Troughs |first=N.|last=Hirata |journal=Journal of Geophysical Research: Planets |date=2023 |volume=128 |issue=3 |doi=10.1029/2022JE007473 |arxiv=2303.14955 |bibcode=2023JGRE..12807473H |hdl=20.500.14094/0100482053 |access-date=2024-03-04 }}</ref>
