Pluto is still considered a planet albeit a "Dwarf Planet" along with Ceres, an Asteroid which was also reclassified and Eris which was labeled a "scattered disk object" which, in some ways resembles an Asteroid belt. The term Dwarf Planet is a bit of a misnomer since these are not a "subset" of Planets themselves but in a different category altogether. Scientists are still debating the differences and definitions of a Plutoid, Dwarf Planet and Planet!

Pluto is a Disney character!

It has been a planet for years and years...so, all of a sudden it isn't a planet???

What is that all about?

I think it is still a planet.

Who knows what is making it have a different orbit. It could be heavier on one side...could have been hit by asteroids who knows what goes on out there. We have not seen it all.

Earth is very lucky, that it has been a long time since it has been really hit.

I don't want to hurt Pluto's feelings.

Having said that, what the difference between a mountain and hill? A rock, a boulder and a pebble? I mean, at what point do they stop being one and become the other?

yes, pluto is, as we define a planet now, too small. however, it is of historic importance and i think affection to leave pluto as the smallest planet. if we wish to add new objects as other small planets, such as charon, that causes no problems.

let's leave pluto a bit of dignity! :P

In 2006, the International Astronomical Union (IAU) issued a formal definition of planet, one that led to Pluto's boot from planethood.

The IAU provided three criteria an object must meet to reach planet status:

A planet is a celestial body that

1. It orbits around the sun.

2. It has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and

3. It has cleared the neighborhood around its orbit.

Sure, Pluto's really a planet if theser are really people.

Wow, voted down for that one? Someone's out to get me I think. Anyway more little people. -why Pluto should be a planet.

I personal think it is a comet like all the other plotoids but fo sure it's no planet. It's orbit is way off form all the other 8 planets and we dont even know if it really is round. So I say it is not a planet.
