The actual reason scientists say it is not a planet is because it has not cleared its orbit of all other debris. With the exception of rogue asteroids and comets, all there planets have cleared their entire orbit of other rocks that may share the same orbit. Pluto has not done this so they do not consider it a planet.

If we left Pluto classified as a planet, then, potentially - there are up to *50,000* objects in the Kuiper Belt Pluto-sized or larger that would also be classified as planets... Better to re-designate one planet as a Dwarf Planet or Kuiper Belt Object than have to name (and Memorize!!) 50,000 new worlds....

Because its too small.
