Pluto demoted
A discovery by Caltech astronomers, announced in New Scientist, effectively demotes Pluto from 9th planet to a large Kuiper belt object along with the newly-discovered Quaoar (don't ask me what it means!). That's interesting enough, but check out this animated graphic of the orbits in question. See the little jitterbug at the center? That's Mercury, Venus, Earth, and Mars zooming around the sun! Those Caltech boys have some sense of humor, eh?
