The planetary debris has settled:
Pluto kicked to the curb

"After a tumultuous week at the 26th General Assembly of the International Astronomical Union (IAU) in Prague, a resolution was passed that defines a planet in our solar system in such a way that only Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune qualify.

"From now on, smaller round objects that orbit the Sun -- including the asteroid Ceres, the former planet Pluto, and the Kuiper Belt iceball with the provisional designation 2003 UB313 -- will be called 'dwarf planets.' The explicit intent of the IAU members who voted with the majority today was that a 'dwarf planet' is not a planet."

This is three-day-old news, of course, but I wanted to provide a segue to a story with a wonderful headline that was on the front page of The Wall Street Journal on Friday: Pluto's demotion divides astrologers, troubles Scorpios.
