The previous post from a few days ago mentioned that the exoplanet count could reach 500 by January according to estimates from astronomers. Well, never mind, it is now only November 20, and the count now stands at 502!
Addendum (November 25):
Scratch that; the number is now 504! Also, see this new abstract regarding at least seven planets orbiting the star HD 10180, the most known for any star so far.
