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.
