Characteristics of the cratering process on small satellites and asteroids

摘要: Photographs of the two known natural satellites Mars - Phobos and Deimos illustrate importance impact cratering in postformational histories moons and, by inference, asteroids other small planetary satellites. The objectives present study are to investigate qualitatively process on bodies, apply some these considerations observed surfaces Deimos, consider briefly light results. bodies is discussed three stages: compression, excavation, modification. Nonescaping escaping ejecta considered.
