Important Notes:
* Dwarf Planets: There are several dwarf planets in our solar system, including Pluto, Ceres, Eris, Makemake, and Haumea. These are smaller than traditional planets but are large enough to be rounded by their own gravity. They are found in the Kuiper Belt and Scattered Disk.
* Moons: Each planet (except Mercury and Venus) has at least one moon. Some planets have dozens!
* Beyond the Solar System: The Oort Cloud is thought to be the outermost region of our solar system, but it's still debated if it actually exists.
