Pluto Day – Remembering the Ninth Planet


Remember when they messed with the universe as we knew it and said Pluto wasn’t a planet? Did your innards violently recoil at the suggestion and make you want to take to the streets and instigate a mutiny against the responsible governing body? In this case, it was the IAU (International Astronomical Union).

I didn’t understand it then, but that didn’t stop me from having a strong opinion. And I was having none of it. I couldn’t accept what they did to Pluto. I’d never given much thought to the planet prior to that announcement, but I suddenly found myself a staunch champion of the planet – just one of many, as it turned out. Other people were also rising up in arms against the injustice done to the ninth planet. Yes, we astronomy non-experts weren’t going to take the experts’ word for it.

Thanks to the very fun and catchy “Dwarf Planet Nothin’” (the video of which can no longer be found on YouTube, but you can still listen to the song here), I found out what was going on. I also learned how to pronounce Kuiper.

Basically, they decided to have a set criteria for planet status qualification in the Solar System:

  • Must orbit around the Sun.
  • Must be big enough to be rounded by its own gravity.
  • Must have cleared is local neighborhood of other large objects.

Apparently, Pluto failed to meet the last requirement since it’s surrounded by other icy Kuiper Belt bodies.

But the fight continued and people who didn’t want to deal with changes in the Solar System they learned in school pushed for Pluto’s reinstatement as a planet. In 2015, word on the street was that it was about to happen. I don’t know what that was about since I couldn’t find anything official classifying Pluto as anything other than a dwarf planet.

People continue to be torn and confused. Officially, Pluto has dwarf planet status, a clear demotion from being Planet No.9, but many scientists are tirelessly working to prove that it deserves to be considered a planet once again. Hopefully, NASA’s interplanetary space probe New Horizons (which has some of Clyde Tombaugh’s ashes, btw) will be able to discover something in aid of this.

Whatever the experts say, Pluto will always be a real planet to me. I’m just waiting for the corroborating evidence, so… Happy Pluto Day, everyone!
