Is Pluto a Planet?

Pluto was discovered in 1930 by Clyde Tombaugh and was initially classified as the smallest and farthest planet in the solar system. However, due to its small size and shared orbit with other celestial bodies, it was reclassified as a dwarf planet in 2006. This decision followed the discovery of Eris, which led to the establishment of new criteria for defining planets by the International Astronomical Union. Despite its reclassification, Pluto remains an important object of study, with missions like NASA's New Horizons continuing to explore its characteristics and surroundings.
