Pluto demoted to dwarf planet in 2006

On August 24, 2006, the International Astronomical Union voted in favor of a strict definition of a planet, ultimately demoting Pluto from the ninth planet from the sun to a dwarf planet — causing controversy both scientifically and culturally.

The IAU, an organization that regulates international professional astronomical activities around the world, has determined that a planet must meet three criteria: it orbits the sun, has a spherical shape and is large enough that its gravitational pull over all other objects of similar size. near his job.

Pluto meets only two of the criteria needed to be a planet. Because it is not gravitationally dominant, Pluto is considered a dwarf planet.

However, only 5% of the world’s astronomers voted for the redefinition, sparking controversy in the astronomy community.

“There are a lot of leading planetary astronomers who are very upset about it,” said Skylar Grayson, a Ph.D. student at Arizona State University.

The reclassification of Pluto also had a wide cultural impact. So much so that the American Dialect Society chose “plutoed” as the word of the year in 2006 – meaning “to give someone or something a lesser position than before.”

“There was a lot of outrage about Pluto’s degradation,” Grayson said. “People had kind of an emotional connection to it. You grew up learning about the nine planets, and then suddenly there are eight.”
