Change of...Planet?

Sixteen years after having successfully recite the planets of our Solar System with ease in my second grade class, it turns out that I was incorrect. Yesterday, the International Astronomical Union (IAU) declared Pluto to be a dwarf planet since its orbit overlapped that of Neptune, which is in direct violation of the new planet qualifications (it has to clear the orbit of other objects).

While this is some amusing news to hear, something even more amusing is the fact that we need to start changing every astronomical textbook in every written language on our planet. And that's no small planetary matter.
