Pluto? A planet?

Personally, I still think it's a planet, because that's what scientists define a planet ---- a satellite that revolves around a larger mass, in this case the sun. So I think it's a bit hypocritical for scientists to refute their claim now, seeing as it is astronomical definition for Pluto to be a planet.
And they demoted it to minor planet......how sad.

And besides, how can it not be. It has a moon and has its own orbit. So yes, I still think Pluto is a planet.
 
I feel bad for whoever had to play Pluto in the school play. His dreams will be crushed.

I do believe that it is a dwarf planet, however. I don't think it is a moon at all. It is just small for its size. Also, like warbourne said, the definition in itself. =D
 
No it's part of the Kuiper belt, which are a bunch of snow ball like bodies about 50 AU away from the sun. Pluto is simply the closest one to us.
 
So it's a part of two systems? 0_o
I always thought it was just part of ours, but meh, that's sounds interesting, I'll look it up.
 
LOL thanks Grim.

And the Kuiper belt is part of our system. Our solar system goes all the way out to the Oort Cloud which is about 50,000 to 100,000 AU from the sun.

If we were to call Pluto a planet, then we would have to call every object of the Kuiper Belt a planet and there's millions of them.
 
All pluto actually is is a tail-less comet pals, sorry. It's classed as a planetoid object, like other massive space rocks and comets and whatnot.
 
That's true.
I just looked it up right now and going by strict definition, Pluto can actually be classified as a comet, as well a dwarf planet.

Only question is, why does it have a moon?
Does that mean it actually has a greater gravitational pull than Ceres (large asteroid) and others?

Asteroids have also been discoverd to have moons, specifically Ida, who has a moon named Dactyl. So it's not just planets that have them.
 
I can answer that part. See, I was watching the news the day scientists said Pluto is not a planet anymore. They said that aa new study shows that in order to be classified as a planet, a surface must have a certain mass, size, and density and must have its own elements. True Pluto has its own elements, but that's it. Its size, mass, and density do not meet the requirements of being a planet.

As for size, Pluto is smaller than our own moon.
