- On the astrology of Charon
- The IAU is talking about changing its definition of "planet" - or, more correctly, actually creating a firm definition of "planet" in the first place because until now it hasn't really been all that clearly defined - and that has raised some interest in the astrology of the potential new planets. I'd like to emphasize, for readers who aren't familiar with how astrology works, that what the IAU decides doesn't really have any direct bearing on astrological practice; astrologers will follow their own traditions and the definitions used in astronomy aren't really part of those. That's why the old canard about the astrological signs not corresponding to the astronomical constellations, falls apart under examination - both are precisely and accurately defined ways of describing locations in the sky, but they aren't identical to each other because they were designed for completely different purposes. However, even though astrologers don't need the IAU to determine what will or won't be astrologically important, the recent public attention to relatively newly-discovered solar system bodies seems like a good opportunity to look at the astrology of new planets.
