What is located beyond the orbit of Pluto?
Kuiper Belt
Kid-Friendly Kuiper Belt Just outside of Neptune’s orbit is a ring of icy bodies. We call it the Kuiper Belt. This is where you’ll find dwarf planet Pluto.
What other bodies are outside of Pluto’s orbit?
So Pluto was demoted to dwarf planet, a status it shares with the other icy, faraway bodies Eris, Haumea and Makemake, as well as the giant asteroid Ceres.
Will Pluto ever clear its orbit?
It orbits the sun and is spherical, so it meets those first two requirements, but it hasn’t cleared its orbit. Pluto, Ceres, Sedna, Eris, and others are now considered to be dwarf planets.
