What would Jupiter look like from Europa?

I am thinking about moving to Europa.

Better do so before Jupiter leaves the Europa Union.

Keeping in mind that the distance from Mars to Earth when Earth is at its fullest separation from the Sun is significantly greater than the Earth to Venus distance under the same conditions, of course.

How much easier would it be for Martians to deduce Heliocentric system? They would have an easy example of another body with a satellite. They have 2 moons themselves. They would have an extra planet with phases.

How about Kepler’s laws?

I’m guessing Europans (at least the ones living on top of the ice) might do quite well.
