NASA doesn't see planets but projects needing funding.
What I meant by my question is kind of along the lines of... every few months, some group releases a study showing that coffee is "bad" for you. Then a few months after that, another group says it is "good" for you. The conflicting studies are endless.
What is to keep another group from releasing a statement that Pluto *is* a planet? I suspect that is exactly what will occur, and most people will continue to refer to Pluto as the 9th planet.
I've always subscribed to theory that Pluto was a Neptune moon that somehow fell out of its orbit.
