How can it be right that one object, the Sun, contains 99% of the mass in our Solar System while everything else has to make do with less than 1%?
In fact, the Sun contains 99.86% of the mass in the Solar System. And
the Sun is 73% hydrogen, so most of the matter in the Solar System is
hydrogen, with the remaining amount being mostly helium, oxygen and
carbon. Everything else, like the metals and rocks is just a tiny
fraction of a fraction of the mass in the Solar System. -factsofworld
