NamingAfter the Nigerian god of agriculture

Achita is a large impact crater on the dwarf planet Ceres. The crater is named after Achita, a Nigerian god of agriculture. The crater was imaged as part of NASA's Dawn mission.[2] The probe showed that Achita has mass-wasting ridges on the floor[3] and is the fourth oldest crater on Ceres having been formed 570 million years ago.[4]
