Astronomers are meeting to define what a "Planet" actually is. This decision could soon affect whether or not Pluto remains a scientifically-defined planet. Currently the argument is a stalemate, according to the article, about 50/50 for both sides. The main issue is Pluto's size. Once believed to be about Earth's, it has since been discovered to be smaller than our moon. Also setting apart is it's odd orbital plane, separating it from other planets. Well call me old fashioned, but i consider Pluto a planet . The argument compares size, but what does that really matter if it exhibits planet-like aspects? I don't know, i guess that's why i'm not an astronomer right? Link.
