Is Pluto a Dwarf Planet? Because it has not cleared the neighborhood around its orbit, Pluto is considered a dwarf planet. It orbits in a disc-like zone beyond the orbit of Neptune called the Kuiper belt, a distant region populated with frozen bodies left over from the solar system's formation.Is Pluto a Dwarf Planet?

the International Astronomical Union (IAU) This day in space science history, Pluto was demoted to “dwarf planet” decades after its discovery and designation as the ninth planet in our solar system. On August 24, 2006, the International Astronomical Union (IAU) made it official when they stripped Pluto of its planet status.
How did Pluto disappear?
