Detailed explanation-1: -In August 2006 the International Astronomical Union (IAU) downgraded the status of Pluto to that of “dwarf planet.” This means that from now on only the rocky worlds of the inner Solar System and the gas giants of the outer system will be designated as planets.
Detailed explanation-2: -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.
Detailed explanation-3: -Poor Pluto. On August 24, 2006 at the International Astronomy Union (IAU) General Assembly the ninth planet was scrubbed only 76 years after its discovery. Even weirder is that it actually got voted out, and by astronomers, not planetary scientists.
Detailed explanation-4: -When Pluto was reclassified in 2006 from a planet to a dwarf planet, there was widespread outrage on behalf of the demoted planet.
