NASA New Horizons Has Decided To Change Astronomical Definitions

Keith's note: Planets orbit stars. Moons orbit planets. Planets and moons are worlds. Our solar system has lots of worlds and no two are the same - Right? "Planet" and "Moon" define where a world is located - not what it is made of. But it seems that NASA's New Horizons mission has decided that they want to unilateraly rewrite the definitions for these terms and, in so doing, confuse everyone.
