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.
Just a guess but I'm guessing the gravitational interaction between the satellite and it's parent body would wreck havoc with the orbit of any body trying to orbit the satellite. Patrick
