WHY WAS HE DEMOTED? What do I mean demoted? Well, Pluto use to be a planet, but that all changed from a change in definition...
Pluto follows 2/3 of this (recently) new criteria, which is: - Is in orbit around the Sun (Tick!) - Has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium shape (Is round. Tick for Pluto!) - Has cleared the neighbourhood around its orbit. That last one is where Pluto fails. It means that it needs to be the biggest thing ALWAYS in it's proximity. And Pluto's orbit falls close enough to Uranus' orbit that it is now a mere Dwarf Planet. ..oh the horror..

So I'm trying to disprove a sound scientific theory?
WELL, NOT EXACTLY.
I believe it should be re-classified. I believe the new definition should be
- Is in orbit around the Sun (Tick!)
- Has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium shape (Is round. Tick for Pluto!)
- Has cleared the neighbourhood in its orbital ring. (Which is now a tick for poor little Pluto!)
You may have noticed this also opens the door for Eris, Pluto's arch enemy, for if it wasn't for him Pluto would still be whole today, but don't worry; I have a 4ᵗʰ term to deny Eris of that privilege.
- Must have a roughly circular orbit.
I add this as, if we look at any other planet, even WITH the old definition, they all have to have circular orbits, as you can observe in this image I have added in below. This just goes to show how Pluto definitely should be a planet.

Have I convinced you yet?
I bet I have. If you want to sign the petition to change the definition, click here. |
