The initial composition of the protoplanetary disk resembles the composition of the Sun, i.e., the Solar System: most was H and He, only 2% were something else, and are often collectively called ›metals‹. A litte more than a quarter of these metals are rocks, from which the meteorites, asteroids and terrestrial planets formed. The rest are various ices, from which the gas giants formed.
