===Other craters=== {{stack| [[File:PIA17661-NASA-DawnMission-Asteroid-Vesta-20131216.jpg|thumb|The crater Aelia]] [[File:Old unnamed equatorial basin on 4 Vesta.png|thumb|[[Feralia Planitia]], an old, degraded impact basin or impact basin complex near Vesta's equator (green and blue). It is {{convert|270|km|0||abbr=on}} across and predates Rheasilvia (green at bottom)]] }} Several old, degraded craters approach Rheasilvia and Veneneia in size, although none are quite so large. They include [[Feralia Planitia]], shown at right, which is {{convert|270|km|0|abbr=on}} across.<ref name="Av-10"/> More-recent, sharper craters range up to {{convert|158|km|0|abbr=on}} Varronilla and {{convert|196|km|0|abbr=on}} Postumia.<ref name="Planetary Names"/> Dust fills up some craters, creating so-called [[dust ponds]]. They are a phenomenon where pockets of dust are seen in celestial bodies without a significant atmosphere. These are smooth deposits of dust accumulated in depressions on the surface of the body (like craters), contrasting from the Rocky terrain around them.<ref>{{cite news |first=J.
