WitrynaThe manner in which an impact crater and its ejecta blanket are created involves an interplay between gravity and the strength properties of the target material. Gravity is important because the overburden stress at depth in an asteroid determines the material shear strength, which affects the mechanics of crater and ejecta formation.
