Points of interest:
The "8" in the Detected Planets entry is not an error. Pluto is not a "planet," but a huge, close-orbiting, low-eccentricity Kuiper Belt object. With a big moon. Of course, some die-hards out there still insist that it really is a planet, more for sentimental reasons than anything else. They're welcome to live in their little fantasy world. Neener neener.
