Question

Quizplus · Accepted Answer

A typical asteroid is composed of rock and metal, with some containing a higher percentage of one or the other. This is based on studies of asteroid samples that have been obtained through asteroid missions and meteorite falls on Earth. Ice or pure ice is not a common component of asteroids, although some may contain small amounts of ice or water trapped within rock or dust.
