History of Pluto Demoted Day
The history of Pluto Demoted Day dates back to August 24, 2006, when the IAU redefined the criteria for classifying celestial bodies. Prior to this decision, Pluto had been considered the ninth planet in our solar system since its discovery in 1930 by astronomer Clyde Tombaugh. However, as our understanding of the solar system evolved, scientists realized that Pluto didn’t fit the new criteria for a planet, leading to its reclassification as a dwarf planet.
