Pluto is no longer a "real" planet.

He is now the retarded cousin of the solar system.

it's gay. kids of future generations will never know just what my very educated mother just sold us nine of.

Well, TECHNICALLY, it's still a planet, but it's a dwarf planet.

Still pisses me off.

You'll always be a planet to me, Pluto.

question is how is this going to mess with astrology? is it? is it not? What about the other bodies they found? And *shudder* Xena?

Actually, the term is "Pluton". So is Charon and 2003UB313, informally known as "Xena". A Pluton is post-Neptune orbiting planet with an eccentric (non-circular) orbit path.

Pluto is still very much a real planet, but the need to actually, physically define planets was real. And there was no way to come up with any meaningful definition of a planet and still have only 9 of them.

So Astronomers went with gravity as the main determinant, specifically gravity strong enough to pull it into a circular shape while still orbiting the star (and not another planet).

As for Charon, Pluto and Charon will be a dual-pluton system, since they orbit each other.

Ceres will also be a planet.

There are at least 12 MORE candidates that will be evaluated for classification over time.

A "pluton" is a rejected term for the dwarf planets - it was a retarded suggestion in the first place, seeing that the word is already used in geology, as a name for some certain rock type.

A bit like the biologists were trying to create a neat difference between trees and shrubberies, and suggesting the word "duck" for the other group.

I stand corrected.

Here's the press releases from the result of the vote at the IAU yesterday/today.

"AU Resolution: Definition of a Planet in the Solar System
Contemporary observations are changing our understanding of planetary systems, and it is important that our nomenclature for objects reflect our current understanding. This applies, in particular, to the designation 'planets'. The word 'planet' originally described 'wanderers' that were known only as moving lights in the sky. Recent discoveries lead us to create a new definition, which we can make using currently available scientific information.

RESOLUTION 5A
The IAU therefore resolves that "planets" and other bodies in our Solar System be defined into three distinct categories in the following way:

(1) A "planet"1 is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.

If Pluto's not a planet anymore... what is it calles then? "Big asteroid"?

A "dwarf planet", or according to the IAU, a celestial body that only satisfies the first 2 of the 3 requirements.
