How appropriate that Starlight get sent to Mars.

Rainbow Dash is like “What do you mean? We’ve been on one together before.” when she and Pinkie go to Jupiter.

@Derpyfan  
Agreed.

@GanymedeSkies  
This is true.

@TychoTMA-1  
The problem could be high up in the atmosphere where there isn’t crushing pressure.

Everyone complaining about Pluto while I’m too busy imagining the literal hell Fluttershy and Rainbow Dash would have to go to.
 
Also I recommend calling up Miss Frizzle for special space suits if any of the ponies are to survive any of this.

@Background Pony #E1BE  
No.

@Derpyfan
 
What I’m saying is that there is a precedent for the definition of the word “planet” being changed. In the early 1800’s, scientists thought there were over twenty before we decided that there should only be seven (Neptune not being known at this time).
 
In the early 2000’s, a whole bunch of large space rocks very similar to Pluto were discovered, enough to bump the number of planets to as many as twenty one if the criteria allowing Pluto to stay were kept.
 
Obviously, this was ridiculous and would make elementary school astronomy class a nightmare, so once again the scientific community put their feet down and decided, yes, there really should be some limits on what should be allowed to be a planet.

Okay, how about this? Pluto is an abandoned planet as if it’s not a planet.

@Dracorex  
What happened to Ceres was bullshit. You wanna drop the other asteroids, fine, but Ceres is a planet and you know it.

@Twitter-Mites  
Gets out while I still can

@GanymedeSkies  
Cue Baldi getting mad at you.

@Twitter-Mites  
No it’s not.

Strangely, in the MLP universe, Pluto IS a planet, and the Earth is flat.

@Dracorex  
So you’re saying people who were born in say 1990 and never knew Ceres as a planet in the first place are hypocrites? Do you see the problem with what you’re saying?

No one complained in the 1850’s when Ceres was demoted. Anyone who cares about Pluto and not Ceres is a hypocrite.

@infinita est lux Solis  
No, it means the moronic definition the IAU came up with doesn’t mean anything. But it never meant anything to people who think for themselves anyway.

@infinita est lux Solis  
Along with Makemake, Haumea, Sedna amongst others.

If Pluto is considered a planet here… Then shouldn’t other dwarf planetoids like Ceres and Eris be here too?

@ImperfectXIII
 
I am still not sure about its exact source, sorry.

@HorsesandMuchMOAR  
Is it from the MLP Facebook or something? Where’s the source?

@ImperfectXIII
 
Some MLP background edited with pictures of planets.

…I’m confused. What is this?

And here we have eight out of nine of the Solar system’s planets.

Well if these do happen, they ain’t coming back.
 
They’d either be crushed, melted, suffocated or frozen.
