National Pluto Demoted Day will be August 24, and we’re getting out our telescopes in order to continue the spirit of planetary research! It’s hard to believe that Pluto, after almost 80 years of being an official planet was finally declassified as a dwarf planet.

 The International Astronomical Union (IAU), determined in 2006 that Pluto was not the dominant object in the sun’s orbit, and therefore could no longer be considered an official planet. It is home to other large bodies, including Pluto’s moon.

PLUTO DEMOTED A DAY: HISTORY

Clyde Tombaugh was the first to discover Pluto in 1930. He made it the ninth planet in our solar system. It is a fairly cold planet, and it exists outside of Neptune’s orbit.

Lowell Observatory received over 1000 suggestions to name the new planet after its discovery. Pluto was named after the Roman god of the underworld.

After the discovery of large objects within its region in 1992, there were questions about Pluto’s status as a planet. One such object was actually larger than Pluto. In 2006, the International Astronomical Union settled on a definition of ‘planet’ that ultimately excluded Pluto. It has been called a “dwarf planet” from that point onward.

A dwarf planet is a celestial body orbiting the sun that is large enough to assume a nearly circular shape but has not cleared the orbital area and is not a Moon.

1930 First Discovered

Clyde Tombaugh discovered Pluto for the first time and determined it to be the ninth planet in the solar system.

1978Pluto’s Largest Moon

2005Other Large Bodies

In 2005 Eris, another dwarf planet with a larger mass than Pluto is discovered in the Kuiper Belt (a region of icy objects that lies outside Neptune’s orbit).

2006 The Demotion

Officially, Pluto is no longer considered a full-size planet by the International Astronomical Union (IAU).

WHY PLUTO DEMOTED DAY IS OUR FAVOURITE DAY

  1. Everyone loves an underdogPluto is the smallest planet in the solar system. It’s easy for people to cheer on this planet. People have been taught for generations that the sun orbits nine planets. Its classification as a dwarf planet has sparked renewed interest in Pluto and other planets in the Milky Way galaxy.

The fascination for the universe there is still many things to be learned about the solar system, and the wider universe in which our lives take place. Pluto’s demotion serves as a reminder of how we continue to learn and investigate, not just our planet Earth but also the sister planets. Reclassifications such as this might be necessary as astronomers and scientists discover new information.
  3. Fun planetsEveryone is interested in planets, no matter their age. No matter if you’re a youngster who is just starting to learn about the solar system or an adult with some astrology knowledge. The prospect of studying planets is tantalizing, much like the dinosaurs. It’s a great excuse to geek out by having a day dedicated to Pluto, the dwarf planet.
