Detailed explanation-1: -Answer. The International Astronomical Union (IAU ) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one-it “has not cleared its neighboring region of other objects.”
Detailed explanation-2: -Pluto was once considered the ninth planet in the solar system. It was demoted in 2006.
Detailed explanation-3: -On Aug. 24, 2006, the International Astronomical Union voted to strictly define a planet, which ultimately downgraded Pluto from the ninth planet from the sun to a dwarf planet-causing controversy both scientifically and culturally.
Detailed explanation-4: -Discovered in 1930, Pluto was long considered our solar system’s ninth planet. But after the discovery of similar intriguing worlds deeper in the distant Kuiper Belt, icy Pluto was reclassified as a dwarf planet.
