Pluto was reclassified as a dwarf planet by the International Astronomical Union (IAU) in 2006. This decision was based on a new definition of what constitutes a planet, which Pluto did not meet due to its inability to clear its orbital neighborhood of other debris. The reclassification sparked significant debate within the scientific community and among the public, as Pluto had been considered the ninth planet in our solar system since its discovery in 1930.
