Vesta's north pole
amateur image processing,
asteroid 4 Vesta,
An approximate map of Vesta's north pole based on publicly released images as of November 2011, compiled by Phil Stooke. It was winter in Vesta's northern hemisphere; the central portion of the map is in winter darkness. Most of that gap will be filled in by the end of Dawn's mission at Vesta.
