I extremely believe that Pluto should in fact be a planet. This "criteria" established by certain scientists is entirely subjective, there is no reason to have certain rules that make pluto not a planet. Why not just work the opposite way and use this criteria for a sub classification of planets. Like "Super" Planets or "These are Deffinetely Planets" Planets. I think that sure science is always changing, but it's seems a little ridiculous that scientist need to downsize Pluto, don't they have better things to do? Like solve our polution problems, or find water on other planets? In conclusion why not let tradition win once in a while?
