Image of the Day: A Crater the Size of Canada on Saturn’s Moon, Mimas


This image, taken by the NASA Cassini spacecraft,  shows Mimas' colossal impact crater 130 kilometers (81 mi) across *wider than Canada), named Herschel after the moon's discoverer, Its walls that are approximately 5 kilometers  (3.1 mi) high, parts of its floor measure 10 kilometers (6.2 mi) deep, and its central peak rises 6 kilometers (3.7 mi) above the crater floor.The impact that made this crater must have nearly shattered Mimas: fractures can be seen on the opposite side of Mimas created by shock waves from the impact on the moon's body.
