The Solar System is what us humans are in. It contains 8 planets, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune in that order.

These planets are seperated in 2 terratories :  Terrestrial, and Jovian.

The Terrestrial terratory has 4 planets, Mercury, Venus, Earth, and Mars. These 4 planets all have a solid surface and have a few or if not no

 moons, and the Jovian Terratory also contains 4 planets, Jupiter, Saturn, Uranus, and Neptune. These planets do not have a solid surface but has

 alot of moons.

There is also the Kuiper belt which contains all the dwarf planets, Pluto, Ceres, Eris, Haumea, and Makemake. These planets look kinda like

 astroids.

After that is the Oort Cloud made of icey debris and it surrounds the Solar System in every direction, and the Oort Cloud is the border between The

 Suns gravitational pull and beyond.

The center of the Solar System is a star called The Sun. Our Solar System is in the Milky Way orbiting around Sagittarius A.
