Now riddle me this: how is it possible that the outer moon moves faster than the one on the lower orbit?

Hmm... ages since I studied physics. If the orbit is stable & circular, the gravitational force and centripetal force should be equal. The mass of the moons cancels out, and so the higher radius orbit is normally slower. So... the higher orbit moon is elliptical or decaying?

Here is another one: if Jupiter rotates around itself in 9h, and the moon around Jupiter in 42h, why does the moon appear to be moving at a higher velocity than the surface below it, despite being seen from 10 Mio km?

I was like argh that’s really hard, but then I remembered it’s probably just parallax

But is the parallax moving in the right direction?
