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 and its moons continue on their way, regardless of how humans try to define them. They will complete their first full orbit since their discovery on Monday, March 23, 2178. It will be closer to the Sun than Neptune again in 2227.
Detailed explanation-3: -Pop Culture. When Pluto was reclassified in 2006 from a planet to a dwarf planet, there was widespread outrage on behalf of the demoted planet.
Detailed explanation-4: -Pluto had been considered the ninth planet since its discovery in 1930, but the IAU-which names astronomical objects-decided in 2006 that a planet must be spherical, orbit the sun and have gravitationally “cleared” its orbit of other objects. Pluto meets two of those requirements-it’s round and it orbits the sun.
Detailed explanation-5: -According to the International Astronomical Union, which sets definitions for planetary science, a dwarf planet is a celestial body that-orbits the sun, has enough mass to assume a nearly round shape, has not cleared the neighborhood around its orbit and is not a moon.
