Sol


 * Proper names: Sol, Helios, The Sun
 * Age: 4800 million years
 * Standard error in age: 0%
 * Heavy element abundance: 100% of Sol
 * Standard error in heavy element abundance: 0%
 * Arity: singular
 * 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.
