Thumbnail for video "The disruption of two planets in a giant impact"

Screenshot of a computer simulation of two planets undergoing a disruptive giant impact. Disruptive collisions are not expected to be common in Solar System formation, and due to numerical effects, the amount of disruption shown here is likely overestimated. The larger (target) body is one tenth the mass of the Earth and the smaller (impactor) body is 70% the mass of the target. The planets are colliding at 3.75 times their mutual escape velocity, which equates to 12.60 km/s. The collision angle, defined by the angle between the velocity vector at impact and the line of their centers of mass, is 5°.

The top-left panel shows mantle and core materials as unique colors for the target and impactor. The top-right panel shows the density of material in kilograms per cubic meter. The bottom-left panel shows temperature in thousands of Kelvins. The bottom right panel shows pressure in Pascals.
