Because Jupiter is about 5.2 times further from the Sun than the Earth, the Sun would be 27 times fainter, but still too bright to look at directly without properly shielding the eyes. Its disk would have an apparent size of 1/5.2 what we see at the Earth, or 6 arcminutes. This means we would probably not easily tell with the naked eye that it has disk-like shape. It would, instead, look like an extremely bright star. Since I do not believe that any of the satellites have the right orbits or sizes, there would be no solar eclipses.
