Pluto is located in what is know to be the Kuiper belt on the outside of our solar system. recently, scientists have discovered tens of thousands of other "planets" in this area, and many of them are as large or larger than Pluto Pluto has characteristics of a planet, like a moon, and an orbit, but because of its size and elliptical orbit, it is not a planet. It is actually the first member of a new category called dwarf planets. the newest dwarf planet is Eris which is slightly larger than Pluto.
