Why WAS Pluto Considered A Planet??

By: Grace Meyers

About Pluto

  • Pluto is now considered a dwarf planet
  • It was too small and has a long orbit, too long of a orbit (since it is the farthest from the sun)
  • Its real name is Plutiod
  • Objects are given this name when they are farther than Neptune
  • There are more PLutiods out there
  • Scientists are aware of this, they think there is wwaaayy more out there and don't bother naming all of them (even though they would all have the same name)
  • Pluto also has 5 moons!!!!!

Back Then, and Now

As you can see, Pluto's image has involved since 1996. It was for scientists to see Pluto and even how small it was( but they couldn't really see how small it was) . It was founded in 1930!!!!!!!!!!!!!!!!!!


PLuto's Moons Include: Nix, Styx, Charon, Kerberos, Hydra

Now The Question...

  • Pluto qualified for 2 out of the 3 qualifacations
  • Size DOES matter!
  • Pluto was discovered a long time ago, it was so long ago that there wasn't any way to tell what it was made of
  • The people who discovered Pluto, also had no way to see all the other objects orbiting around the sun (like asteroids and comets)
  • They also had simpler a definition for planets, the definition was that: Every new object was considered a planet (Pluto fit that category)
  • At one point they considered 14 objects as planets
  • As science expanded and we were able to distinguish asteroids and comets, and planets and giant balls of ice!
  • The definition of planets changed, leaving less planets in the solar system
  • Pluto was no longer considered a planet in 2006, when they re-defined the definition of Pluto :(
