The IAU decides to re-define planet, and Pluto gets the boot.
I learned the planets in first grade, faithfully memorizing them in order of distance from the Sun. So that’s like thirty-five years ago. I’m too old to un-learn Pluto.
I mean, I understand that the actual science is more important than the romantic or nostalgic aspects. The IAU is the controlling legal authority here in these matters.
But still, Pluto’ll always be my Pluto.
