Oxo {{IPAc-en|ˈ|ɒ|ʃ|oʊ}} 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.{{cite web|title=Planetary Names: Crater, craters: Oxo on Ceres|url=http://planetarynames.wr.usgs.gov/Feature/15383|website=Gazetteer of Planetary Nomenclature|date=21 September 2015}}

Formation

Oxo is a very young crater, having been formed only {{val|190|100|70}} ka (thousand years) ago,{{harvnb|Nathues|Platz|Hoffmann|Thangjam|2017|p=1}} and it is entirely located within the older, heavily degraded crater Duginavi.{{harvnb|Nathues|Platz|Hoffmann|Thangjam|2017|p=9}} 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.{{harvnb|Nathues|Platz|Hoffmann|Thangjam|2017|pp=3-4}}

Physical features

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.{{harvnb|Nathues|Platz|Hoffmann|Thangjam|2017|p=3}}

Oxo is actively undergoing the sublimation of water ice, due to its young age. This ice is located along the crater's southern wall.{{harvnb|Formisano|Federico|Magni|Raponi|2018|p=2}}
