CNN PASADENA, California (CNN) -- A group of astronomers announced Friday that an object they discovered in the distant reaches of the solar system is large enough to be classified as the 10th planet -- a claim likely to reignite a debate over just how many objects should really have the title of planet.

The object -- located 96 times as far from the Earth as the Earth is from the sun, or nearly 9 billion miles away -- was first photographed in October 2003 by astronomers at the California Institute of Technology's Palomar Observatory, north of San Diego.

While researchers say they aren't yet sure of its actual size, they have determined the object is bigger than Pluto, currently the smallest planet and the one most distant from the sun.

"If Pluto is a planet, it seems reasonable that something that's bigger than Pluto, and further away than Pluto, should be called a planet, too," said Mike Brown, a Cal Tech planetary scientist who made the discovery with colleagues Chad Trujillo of the Gemini Observatory and David Rabinowitz of Yale University.

However, a number of astronomers dispute whether Pluto, discovered in 1930, should really be classified as a planet, because it is so dissimilar from the other eight. Instead, they believe it should be classified only as a Kuiper Belt object, part of an array of icy debris in the outer reaches of the solar system.

Thousands of Kuiper objects have been discovered, and more are being found all the time.

Brown concedes that both Pluto and his new planet are Kuiper objects -- but he argues they are also both big enough to be classified as planets.

The International Astronomical Union, the official arbiter of such disputes, has classified Pluto as a planet and recently declined to demote it. Brown said resolving the argument over whether the object his team found is a planet will take years.

Brown's team has submitted a name for its proposed planet to the IAU, which won't be announced until the astronomy group hands down its ruling.

While the object was first photographed in 2003, its motion was not detected until January because it was so far away. Since then, astronomers have been studying the object to estimate its size and motion.

Brown said the planet-sized object probably wasn't discovered earlier because it was in a location where planets aren't expected.

"All of the planets are in a disc around the sun, and this object is 45 degrees out of that disc," he said.

--CNN Producers Sara Weisfeldt and Kate Tobin contributed to this report.

I for one think that the 'object' should be classified as a planet since it is bigger than pluto. I hope that the IAU accepts the proposal to name the 'planet' and finally, we can prove the textbooks flawed. winkx.gif

Wasn't it originally called Planet X? I remember the discovery of a new "object" back a couple of years that was bigger than Pluto but still in our Solar system. I Hope it gets approved as well, i wouldn't mind having a new planet in the Solar system. :)

there already is a 10th planet that was found if I remember correctly, some said it was too small to be classified a planet

i heard about 2 years ago that they had found a 10th planet, which was similar in size to pluto and that it was called Quaorar or something like that [color=green]

"All of the planets are in a disc around the sun, and this object is 45 degrees out of that disc," he said.

[color=black]and what the hell, how can it be 45 degress out of a disc??[/color][/color]

45 degrees above maybe? I heard of the planet that Mihail is talking about too.... I think it was about 3/4 the size of pluto, but I don't remember what it was called. I guess they decided that one wasnt a planet.

Another 10th planet?

Just send a missile at the rock and blow it up. I like 9 planets, thank you very much.

I wish they would move on with the debate on whether or not Pluto was a planet or not. It's been over 75 years, a bit too long to turn everything back. At the time it was discovered nothing else around it was found and called a planet, it has some significance. The debate should only apply to new objects found. As for this "10th" planet, I wonder how long it takes to make a complete revolution around the sun...

not pluto another planet they found.

the "11th" planet takes 500 or so years.

Pluto has been the center of debate on whether or not it should be classified as a planet or not for years... And what is this 11th planet? :Puzzled:

I'm never going to this new planet, so I don't care :p Let's just use it as an excuse to celebrate! *pops the cork on the champagne*
