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] The crater floor also features a system of fractures, mostly located in the southern part of the crater.[3]
The center of Dantu is contains a peak, with a ring complex around it.[4] The majority of Dantu's pit craters surround this feature, with said pit craters largely ranging between 400 and 900 metres in diameter.[4]
