Eponym Annona (mythology), god of the harvest in Ancient Rome. [2]

Annona is a crater on the surface of the dwarf planet and large asteroid Ceres. It is a corner of the Sintana Quadrangle, located northwest of the namesake crater. [3] It is named after the Roman Mythology agricultural deity of the harvest much like other craters on Ceres. [4] Its name was officiated on December 14, 2015 by the International Astronomical Union. [1]

Annona is a preservation class 3 crater, meaning that it is a crater with a flat bottom and its walls are degraded. [5] It is believed that this degradation was due to the formation of a young crater along the rim of Annona. [3]
