Why the Model of a Hydrogen-Filled Sun Is Obsolete

Isotope analyses on meteorites, planets, lunar samples, the solar wind, and solar flares show that heterogeneous debris of a supernova (SN) that exploded here 5 Gy ago formed the solar system. The Sun formed on the collapsed SN core. Iron meteorites and the iron cores of the terrestrial planets formed out of iron-rich material surrounding the SN core. Giant gaseous planets formed out of the light-weight elements in the outer SN layers. Mass separation enriches light elements like H and He at the solar surface, but the bulk Sun consists almost entirely of the same seven, even-numbered elements that comprise 99% of ordinary meteorites - iron (Fe), oxygen (O), nickel (Ni), silicon (Si), magnesium (Mg), sulfur (S) and calcium (Ca).
