Why aren't planets called "star-moons"? Then moons would be star-moon moons. ;-) I found it interesting that the Pluto-Charon orbital barycenter isn't inside Pluto, leading some astronomers to consider it a "double planet", er, "double dwarf planet", or whatever it is.

Some one trying to explain Pluto's existence. The square peg never fit in the round hole. In order to be a moon, Pluto would have to orbit Neptune. It doesn't, it orbits the sun. :)
