Solar System Expansion
If the International Astronomical Union has its way, the solar system will immediately expand to include 3 new planets, Ceres, currently considered a large asteroid; Charon, now considered a moon of Pluto; and Xena, a recently discovered object that is larger than Pluto. And may even grow to ~100!
The executive committee of the IAU has approved a new definition of what constitutes a planet, and a vote of the union's general assembly is scheduled for Aug. 24th.
The Boston Globe has the fascinating article here . The article is worth a read and you can click on a larger photo that makes a wonderful visual aid.
I guess this destroys the old pneumonic device for remembering the planets...
