General Information on the Planets
What are some good Web sites for information on the planets in our solar system?
For info on the planets please see either NASA JPL's Welcome to the Planets or the University of Arizona's The Nine Planets Web sites.

An object bigger than Pluto has been found in the outer solar system by astronmers Mike Brown (Caltech), Chad Trujillo (Gemini Observatory), and David Rabinowitz (Yale University). It is possible, perhaps likely, that it will eventually be considered to be our solar system's tenth planet. For more info, see NASA's press release and the discoverer's web site. Its temporary designation is 2003UB313; an official name will be given in due course (more). Brown et al have now also spotted a moon orbiting this object.
