Pluto Demoted Day History

On πŸ—“οΈ August 24, 2006, a pivotal moment in astronomy occurred when the International Astronomical Union (IAU) voted to redefine the criteria for classifying a celestial body as a planet. This decision led to the reclassification of Pluto from the ninth planet to a dwarf planet, generating both scientific and cultural debates. The IAU’s criteria require a celestial object to orbit the sun, have a spherical shape, and exhibit gravitational dominance by clearing its orbit of other similarly-sized objects.

Pluto met only two out of these three criteria, resulting in its classification as a dwarf planet. However, the decision was met with controversy, as only a small percentage of the global astronomical community participated in the redefinition vote.

The reclassification had significant cultural implications as well. The term “plutoed” was even chosen as the 2006 Word of the Year by the American Dialect Society, signifying the act of relegating someone or something to a less important status.

Quick Facts About Pluto

Planet Reclassification: Pluto was considered a planet until 2006 when it was reclassified as a dwarf planet.

Proximity to the Sun: At times, Pluto is closer to the Sun than Neptune, which is further out in the solar system.

Size Comparison: Pluto is smaller than Earth’s moon, making it relatively tiny.

Lengthy Year: A single year on Pluto is equivalent to 248 Earth years due to its long orbital period.

Long Day: A day on Pluto is around 153 hours, about six Earth days.

Multiple Moons: Pluto has five known moons, including Charon, its largest moon.

Distant Realm: Pluto resides within the Kuiper Belt, a region beyond Neptune populated by icy objects.

Discovery: Pluto was discovered on February 18, 1930, by astronomer Clyde Tombaugh.

Size: Pluto is much smaller than Earth and even some moons in the solar system.

New Horizons Mission: NASA’s New Horizons spacecraft provided detailed images and data about Pluto during its flyby in 2015.
