What's Happening?
On August 24, 2006, the International Astronomical Union (IAU) reclassified Pluto from a planet to a dwarf planet, a decision that sparked widespread debate and interest in the scientific community and among the public. This reclassification was based on new criteria for defining planets, which Pluto did not meet due to its size and the characteristics of its orbit. The decision was part of a broader effort to better categorize celestial bodies in our solar system, leading to the recognition of other dwarf planets.
