EponymAfter the Candomblé god of agriculture

Oxo /ˈɒʃ/ is a small impact crater on the dwarf planet Ceres. Located in Ceres's northern hemisphere, it is the second-brightest feature on Ceres, after Haulani Crater. The crater was named after the Candomblé (and Yoruba) god of agriculture.[2]

Formation[edit]

Oxo is a very young crater, having been formed only 190+100
−70
Ka (thousand years) ago,[3] and it is entirely located within the older, heavily degraded crater Duginavi.[4] Despite its relatively small size, the impact that created Oxo penetrated more deeply into Ceres than many larger craters, reaching a depth of 4,802 metres, and it excavated significant amounts of bright material that was distributed unevenly throughout the crater's ejecta blanket.[5]

Physical features[edit]

As a result of Oxo's young age it has a very sharp crater rim and a well-defined ejecta blanket. It is also home to many large boulders; boulders produced by older craters have largely been destroyed by micrometeoroid impacts.[6]

Oxo is actively undergoing the sublimationofwater ice, due to its young age.[3] This ice is located along the crater's southern wall.[7]
