As I was reading an article about "binary" asteroids, I wondered if there might be known planetary satellites with moons of their own? Sizable moons that could conceivably be seen from the satellite's surface under favorable conditions; not boulder-sized stuff which certainly must exist. Anyone know if such things have been found to date? I'm too beat to keep my eyes open and look it up. Bed beckons. __________________________________________________ Do You Yahoo!? Tired of spam?
