Since it's not a planet, what is it?
Is it a Dwarf Planet?
What is a Dwarf Planet anyways :S
(I got the Dwarf Planet info off some pluto info thingie D:)

No no, how the hell is Pluto a star?
It was considered a Planet.. I'm sure even WE can distinguish planets between stars :S
I don't remember clearly, but I THINK I asked my teacher what Pluto is. She said she wasn't sure, and someone interrupted her and asked if it was a star. I think she said no (?)

dwarf planet ala wiki
http://en.wikipedia.org/wiki/Dwarf_planet
a dwarf planet is a celestial body within the Solar System that satisfies these four conditions:
* is in orbit around the Sun
* has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (near-spherical) shape
* has not cleared the neighbourhood around its orbit
* is not a satellite
"has not cleared the neighbourhood around its orbit"
is the only point that distinguishes pluto as different than the others.

It is now labelled a "dwarf planet", like Ceres and Eris.
The International Astronomical Union defines a dwarf planet as:
- in orbit around the Sun
- has enough mass for its gravity to cause it to be a spherical shape
- has not cleared the neighbourhood around its orbit of other objects
- is not a satellite of another planet
Some pluto info thingie - I'll have to look that one up, I've never heard of that before. Must be a new astronomical term I need to learn more about.

Pluto is a "Dwarf Planet"
Ironically, The definition of a dwarf planet includes the words "a dwarf planet is not a planet".
Also ironically, under the new definition, Jupiter would not be a planet either because it "...has not cleared the neighborhood around its orbit...".

Pluto is now considered a part of a new system known as "ice worlds" which consist of ice dwarf worlds which Pluto has now become. The systems consist of Pluto, Eris, Quaoar and maybe Sedna.

your right its a dwarf planet, some can be called plutons.
a planet needs to have all 3 of the following
1. enough mass to make it atleast mostly sphereical.
2. it has to oribt a star. it cannot be another star or a satellite of another planet.
3. it has to clear its orbit of debris.
pluto and other dwarf planets do not meet the 3rd rule because they are in the kuiper belt full of comets and dont have enough gravity to clear them away.

Wow to the people saying pluto is now a star.
Almost as bad as saying the earth is flat.

Pluto is not a star because it can't produce its own light...its a lost asteroid I think...

Pluto isn't actually a planet. it is now considered a star. =]
