The new definition of a planet includes "that an object be massive enough that gravity has formed it into a sphere and that it circles a star and not some other planet." Not everybody is happy about this:
The difference, according to the definition, is that the center of gravity for Pluto and Charon is between them, not inside either one. So technically, Charon is not orbiting Pluto but is orbiting the center of gravity of the two bodies. The center of gravity for the Earth and its moon, on the other hand, is inside the Earth. Dr. Boss calls this 'a legalistic definition.'Gods save us from legalistic definitions!
One wonders what Holst would have made of all this. A four-movement sequel. The Planets, II, I think. Subtitled "Pluto's Revenge," or somesuch. I'm sure Hollywood would make a movie out of it.
I'm sure that if Holst lived now he'd probably have a computer manned by a monkey who would bang something out that he could sell as a cheap but lucrative sequel. It worked for Michael Crichton didn't it?
