What are the contents of our solar system?

Answer 1

From a mass standpoint, the best answer is "The Sun, Jupiter, Saturn, and miscellaneous debris."

More specifically: other than the Sun, which is nearly all the mass of the solar system, there are 8 planets, satellites of those planets (a couple of hundred of these), asteroids, Kuiper belt objects (and what are sometimes called "trans-Neptunian objects" for lack of a better name), the Oort cloud, and weirder things like comets and the rings of the outer planets.

Answer 2

There are gases, rocks called meteoroids, ice chunks, antimatter, energy, like heat, and more, like probably human matter from space stations!!
