Today’s vote by the International Astronomers Union has just redefined what a planet is and under the new guidelines, poor Pluto gets the boot. It will now be known as a “dwarf planet”. The ruling also reverses an earlier proposal that would have kept Pluto and added Ceres, Pluto’s moon Charon and Xena to the list. Blogger Phil Plait, who unlike me is actually an astronomer, was unsatisfied about that one, and I was too, but not for entirely the same reasons. I agree that adding lots of arbitrary definitions and exceptions to a definition confuses the matter greatly. So I figure we should simplify. [...] [...] Poor Pluto just got demoted!

Basically Pluto and Neptune swaps neighbourhoods. 1 (c) has cleared the neighbourhood around its orbit:
