Oct 13, 2022 · Pluto's so-called demotion from planetary status raises larger issues about how to define any object in the solar system, or even in space more generally. It shows that science...
Pluto is now classified as a dwarf planet because, while it is large enough to have become spherical, it is not big enough to exert its orbital dominance and clear the neighborhood surrounding its orbit.
Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most- massive known object to directly orbit the Sun .
Jul 13, 2015 · For more than 70 years, Pluto was one of nine planets recognised in our Solar System. But in 2006, it was relegated to the status of dwarf planet by the International Astronomical Union (IAU)....

Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
Pluto is not a planet because the International Astronomical Union (IAU) requires certain criteria that it does not meet. As of 2021, Pluto is a dwarf planet that hasn't cleared its neighboring region.

Pluto is a dwarf planet located in a distant region of our solar system beyond Neptune known as the Kuiper Belt. Pluto was long considered our ninth planet, but the International Astronomical Union reclassified Pluto as a dwarf planet in 2006.
Discovered in 1930, Pluto was long considered our solar system’s ninth planet. But after the discovery of similar intriguing worlds deeper in the Kuiper Belt, tiny Pluto was reclassified as a dwarf […]
