Geological map of the asteroid Vesta. High-resolution geological map of the minor planet and asteroid Vesta is derived from Dawn spacecraft data. Brown colours represent the oldest, most heavily cratered surface. Purple colours in the north and light blue represent terrains modified by the Veneneia and Rheasilvia impacts, respectively. Light purples and dark blue colours below the equator represent the interior of the Rheasilvia and Veneneia basins. Greens and yellows represent relatively young landslides or other downhill movement and crater impact materials, respectively. Vesta is one of the two largest bodies in the asteroid belt, being around 525 kilometres across. Dawn was launched in 2007, and arrived at Vesta in 2011. Image published in 2014.
