Utopia Planitia Crater

This unnamed crater in Utopia Planitia is shaped like a peanut shell, with an indentation in the crater rim at the middle of the crater. It is likely that this crater was created by a dual impact. In a dual (or double) impact the incoming meteor is broken into two or more pieces which impact together into the surface. This type of impact often has a unique ejecta blanket shape, pinched at the center making a butterfly shape, and a pronounced inner rim jutting out at the center.
