The 6-mile-wide (10-kilometer-wide) crater named Oxo is the second-brightest feature on <a href="https://en.wikipedia.org/wiki/Ceres_(dwarf_planet)" class="extiw" title="w:Ceres (dwarf planet)">Ceres</a>. Only <a href="https://en.wikipedia.org/wiki/Occator_(crater)" class="extiw" title="w:Occator (crater)">Occator's</a> central area is brighter. Oxo lies near the 0 degree meridian that defines the edge of many Ceres maps, making this small feature easy to overlook. NASA's <a href="https://en.wikipedia.org/wiki/Dawn_(spacecraft)" class="extiw" title="w:Dawn (spacecraft)">Dawn</a> spacecraft took this image in its low-altitude mapping orbit (<a href="https://en.wikipedia.org/wiki/Dawn_(spacecraft)#Ceres_orbit" class="extiw" title="w:Dawn (spacecraft)">LAMO</a>), at a distance of 240 miles (385 kilometers) from the surface of Ceres.
<p>Oxo is also unique because of the relatively large "slump" in its crater rim, where a mass of material has dropped below the surface. Dawn science team members are also examining the signatures of minerals on the crater floor, which appear different than elsewhere on Ceres.

</p><p>Dawn's mission is managed by JPL for NASA's Science Mission Directorate in Washington. Dawn is a project of the directorate's Discovery Program, managed by NASA's Marshall Space Flight Center in Huntsville, Alabama. UCLA is responsible for overall Dawn mission science. Orbital ATK, Inc., in Dulles, Virginia, designed and built the spacecraft. The German Aerospace Center, the Max Planck Institute for Solar System Research, the Italian Space Agency and the Italian National Astrophysical Institute are international partners on the mission team.
