Pluto Not a Planet, Astronomers Rule

Pluto has been voted off the island.
The distant, ice-covered world is no longer a true planet, according to a new definition of the term voted on by scientists today.
"Whoa! Pluto's dead," said astronomer Mike Brown, of the California Institute of Technology in Pasadena, as he watched a Webcast of the vote. "There are finally, officially, eight planets in the solar system."
In a move that's already generating controversy and will force textbooks to be rewritten, Pluto will now be dubbed a dwarf planet.
But it's no longer part of an exclusive club, since there are more than 40 of these dwarfs, including the large asteroid Ceres and 2003 UB313, nicknamed Xena—a distant object slightly larger than Pluto discovered by Brown last year.
"We know of 44" dwarf planets so far, Brown said. "We will find hundreds. It's a very huge category."
A clear majority of researchers voted for the new definition at a meeting of the International Astronomical Union (IAU) in Prague, in the Czech Republic. The IAU decides the official names of all celestial bodies.
The tough decision comes after a multiyear search for a scientific definition of the word "planet." The term never had an official meaning before.
Pluto. It's a dwarf star or something now.
Pluto is now considered a "dwarf" planet, because it's too small and it doesn't meet the new criteria for calling something a planet
Pluto!
Err.I might be wrong but i think it is earth
Pluto...Duh
I hate pluto,good,they finally got it off the solar system!
PLUTO, but the jury is still out on that one, my opinion if they change it now they change history and I mean i wouldn't like it if I had a god called pluto because I could see it and now it is a moon of a planet or a dwarf planet, they decided that it should be a planet back then so keep it a planet, work around it!
Pluto according to new planet "requirements". Who said Earth...ha ha. oh please tell me that's a joke. seriously!
Pluto coz it goes farther away from the Solar System every minute.
Actually, in my opinion, none of the above is correct. If we go by the new definition voted in by the IAU, only Mercury and Venus qualify as planets, so there are now only two. Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto, have not cleared their orbital paths which is one of the new criteria for planets. It seems likely that the IAU will reject this definition which was voted upon with not even a quorum at the last meeting. If they go back to the definition that was introduced at the start of the meeting, we are looking at 14 or more planets which also seems unacceptable, therefore the original 9 should stand until a suitable definition is agreed upon.
Pluto is now considered part of a newly found cosmic belt made up of asteroids and comets that encompasses our solar system.
