Meteoritics may be defined independently of meteorites and meteors, however, as that branch of astronomy that is concerned with the study of the solid matter that comes to the Earth from space; of the solid bodies of subplanetary mass that lie beyond the Earth; and of the phenomena that are

The presence or absence of certain minerals is indicative of physical and chemical processes. Impacts on the parent body are recorded by impact-breccias and high-pressure mineral phases (e.g.
