Edit: Pluto isn't a planet in my opinion because it is smaller than our moon which is not catagorized as a planet. If the term 'planet' verses the term 'moon' or 'asteroid' are dependant on size, then pluto would be a moon or asteroid. If, however, the terms 'planet', 'moon', and 'asteroid' also take into acocunt location, revolution, and orbit, then it's possible that we have hundreds of planets. Kinda makes me think....
