the Solar System The solar system includes the sun and everything that orbits it. This includes the planets, dwarf planets, comets, and asteroids. There are eight planets in the solar system and they are grouped into inner and outer categories depending on what there made of. The four inner planets, the terestrials, are closest to the Sun. They are rocky and metallic. The other four planets, the outer ones, are made of hydrogen and helium. They are called the "giants" because their size and their orbits are ten times larger than the sizes and orbits of the terestrials. There are five dwarf planets that orbit the sun including Pluto. According to T__he Story of the Solar System__ by Mark Garlick, the sun took fifty million years to make. The sun is the center of the Solar System. All eight planets orbit the Sun and all but three spin counter clockwise.
