How big?
In looking a bit more at the scale of the orbits of Jupiter's outer moons, I was astonished to find that the diameter of the orbits would cover 3° across the sky - at Jupiter's current position (about the width of Orion's Belt. When at opposition (and therefore at about the closest distance) the outermost moons orbits would cover 5° of the sky - more than the distance between Castor and Pollux.
It surprised me at least.
