Sixty-Three

I noticed today, for no particular useful reason, that Jupiter has sixty-three satellites. Sixty-three. You know, I was deeply interested in astronomy when I was in grade school, but to the best of my recollection, there were ten, perhaps fifteen at the most, back in the day.

(This was suggested as a good place to look for a name for the kitten, should he take up permanent residence here, but nothing seemed appropriate. I've become partial to "Jasper," myself.)

And did you know? There's a minor planet, Ceres, in the asteroid belt, as well. (A probe is scheduled to explore it in 2015.) How did I miss this?
