The outer regions of a protostar form
WebbChemical composition of stars (from spectra) is fairly constant: 73% Hydrogen, 25% Helium, 2% Other Elements. Masses of stars range from 1/10 M Sun to about 50 M Sun . … WebbThus, the planetesimals that formed in the outer solar system are composed primarily of hydrogen compounds with traces of rock and metal. Hydrogen and helium do not …
