Pluto was reclassified from a planet to a "dwarf planet" in 2006 by the International Astronomical Union (IAU) due to its inability to clear its orbit of other debris. While it orbits the Sun and has enough mass for its gravity to form a nearly round shape, it shares its orbital zone with other objects in the Kuiper Belt. This redefinition aimed to provide clearer criteria for what constitutes a planet. Hence, Pluto's status changed, reflecting our evolving understanding of celestial bodies.
