The small, bright crater Oxo on Ceres is featured in this image from NASA's Dawn spacecraft. Oxo (6 miles, 10 kilometers in diameter) is located at mid-latitudes on Ceres and likely has water ice.
Dawn took this image on Oct. 17, 2016, from its second extended-mission science orbit, at a distance of about 920 miles (1,480 kilometers) above the surface. The image resolution is about 460 feet (140 meters) per pixel.
