The Solar System is made up almost entirely of hydrogen and helium. A solar system consists of a star, for us, the Sun, and everything that is drawn and bound to it by gravity. For us, these include the planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, dwarf planets like Pluto, as well as the dozens of moons, and the millions of asteroids, comets, and meteoroids.
