If Pluto is a planet, so would be Eris, Sedna, Haumea, Makemake, Chorion, and Pallas.
So how many planets are in our solar system?
8 (or 9 if you include the one that almost certainly exists in the Kepler belt that is about the size of Neptune)
Or 15 (16 once again if you include the highly probable 5th Gas Giant)

It's kuiper belt not Kepler belt bud, but yeah if you counted all the pluto sized object in there the school kids will have a hell of a time remembering them all, it would add up to over 100 planets.
