Yes, Pluto is in the Kupier Belt however, the reason it is included in the planetary list for Sol is that it's orbit is in the approximately the same plane as the other eight planets, albeit, Pluto rotates the sun in the opposite direction from the others.
Additional arguments can be garnered for Pluto?s planetary authenticity by considering Charon, Pluto?s moon. As both Pluto and Charon share synchronicity with respect to each other, it is theorized that they were once one mass and became separate because of a gigantic impact. with an unknown body.
2003 UB313 will never replace Pluto as the 9th planet, nor will it ever attain status as the 10th planet (IMHO) due to the fact that 2003 UB313?s orbit is oblique with respect to the rest of the solar system.
