LOS ALAMOS, N.M., Aug. 10, 2020—New 2D and 3D computer modeling of impacts on the asteroid Psyche, the largest Main Belt asteroid, indicate it is probably metallic and porous in composition, something like a flying cosmic rubble pile. (...)
The team provides the first 3-D models of the formation of Psyche's largest impact crater, and it is the first work to use impact crater models to inform asteroid composition. The 2-D and 3-D models indicate an oblique impact angle where an incoming object would have struck the asteroid's surface, deforming Psyche in a very specific and predictable manner, given the likely materials involved.
Metals deform differently from other common asteroid materials, such as silicates, and impacts into targets of similar composition to Psyche should result in craters similar to those observed on Psyche. (...)
