Numisia AV-L-21

This image of Numisia AV-L-21, from the atlas of the giant asteroid Vesta, was created from images taken as NASA Dawn mission flew around the object, also known as a protoplanet. The set of maps was created from mosaics of10,000 images from Dawn's framing camera instrument, taken at a low altitude of about 130 miles (210 kilometers). This map is mostly at a scale about that of regional road touring maps, where every inch of map is equivalent to a little more than 3 miles of asteroid (one centimeter equals 2 kilometers). http://photojournal.jpl.nasa.gov/catalog/PIA19525
