Emily Lakdawalla reports on the recent discovery of four (as yet unnamed) moons orbiting Saturn. So far that makes 60, none of which can make a decent cocktail.
These new moons, like many of Saturn's, are about half the size of Deimos, which is pretty small. The curious should click through if they wish to see an animation of the discovery images for one of the newly found satellites.

And planet speaks mostly to mass and location, not composition.

I hope you will take it as a compliment when I say you are often difficult to respond to because thought and often research are required.

I hope you will take it as a compliment...
Oh, hell, yeah! I'll take it any way I can get it...
