Two planets merging by giant impact

October 26, 2023

#### Two planets merging by giant impact

link

Computer simulation of two planets undergoing a giant impact that results in a merger (accretion). 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 1.08 times their mutual escape velocity, which equates to 3.63 km/s.

#### Two planets undergoing a hit-and-run impact

link

Computer simulation of two planets undergoing a hit-and-run giant impact. This style of collision comprises around half of the giant impacts expected to occur during the latter stages of Solar System formation. 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 disruption of two planets in a giant impact

link

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.
