There is a pretty solid definition of a planet. I can't remember what exactly it is, but Pluto does not conform to the definition. Not anymore.
Pluto is also too close to the Oord cloud and even in the Oord cloud itself there are hundreds if not thousands of objects larger than Pluto. So we would need to add hundreds or even thousands of objects as planets or remove planet status of Pluto.

Not sure why that joke popped into my head at this time :)
