| Naming | Dantu, the Gã god of planting |
Dantu /ˈdæntuː/ is a large crater on Ceres, located within the Vendimia Planitia. It is rimmed by a number of minor faculae, which together form Bright Spot 2.
Etymology[edit]
The crater is named after Dantu, the timekeeper and first god of planting (millet) of the Gã people of Accra, Ghana.[2]
Formation[edit]
Dantu is thought to have formed 230+30
−30 Ma (million years) ago, based on the amount of crater impacts present within its ejecta blankets.[3]
Physical features[edit]
The walls of Dantu are quite heavily eroded, with most of the north-eastern wall having collapsed completely.[3] Due to Dantu's relatively young age its crater floor is smooth, with few additional craters present within it.[3] Dantu's floor is also home to a system of fractures, which are mostly located in the south of the crater.[3]
The center of Dantu is home to a peak, with a ring complex around said peak.[4] The majority of Dantu's pit craters surround this feature, with said pit craters largely being between 400 and 900 metres in diameter.[4]
