It's still a planet, only it's put into a new class known as "dwarf planets" which includes all the other round Kupier Belt Objects (icy worlds) in the outer reaches of the Solar system and maybe some of the larger asteroids, as opposed to "major planets" (Mercury, Venus, Terra, Mars, Jupiter, Saturn, Uranus, and Neptune) and "minor planets" (asteroids). My father, an astronomer, has noted the whole debate is strictly one of terminology, so there isn't really any "wrong" solution as to what a planet is.
