Ali Baba is a large crater in the northern hemisphere of Saturn's moon Enceladus. Ali Baba was first discovered in Voyager 2 images. It is located at 57.2° North Latitude, 12.0° West Longitude and is 35 kilometers across. Ali Baba has a large dome in its interior, suggesting the crater has undergone viscous relaxation. The top of the dome even reaches higher than the crater rim.
