Kerwan Crater, at 174 miles (280 kilometers) in diameter is the largest crater that Dawn has discovered on Ceres. A portion of its jagged rim runs from the top left to bottom center of this image. Kerwan was named for the Hopi spirit of the sprouting maize. Dawn took this image on Oct. 19 from its second extended-mission science orbit (XMO2), at a distance of about 920 miles (1,480 kilometers) above the surface. The image resolution is about 460 feet (140 meters) per pixel. http://photojournal.jpl.nasa.gov/catalog/PIA21232
