Introduction to Pluto Demoted Day
Pluto Demoted Day is observed every year on August 24th to remember the historic moment in 2006 when Pluto was reclassified from a planet to a dwarf planet. Once considered the ninth planet in our solar system, Pluto’s status changed due to new scientific criteria defined by the International Astronomical Union (IAU). This day serves as a reminder of how science evolves with knowledge and research.
The History of Pluto’s Demotion
Pluto was discovered in 1930 by astronomer Clyde Tombaugh and was celebrated as the ninth planet of our solar system for over 75 years. However, in 2006, the IAU introduced a new definition of a planet. According to the new definition, a planet must:
-
Orbit the Sun.
-
Be spherical in shape.
-
Clear its orbit of other debris.
Pluto met the first two criteria but failed the third. As a result, it was reclassified as a dwarf planet, sparking debates, nostalgia, and a mix of emotions among astronomers and space enthusiasts alike.
