Kebira crater

The Kebira crater is an impact crater 31 kilometres wide, the largest in the Sahara (of a diameter which is twice that of the second largest known crater in the region). Discovered from satellite photos in March 2006 by Boston university researchers Farouk El-Baz and Eman Ghoneim, it is thought to be the result of the impact of a 1.2 kilometre wide meteorite on Earth. The date it was formed has not yet been established.
