This question already has an answer here:

Humanity is about to leave our solar system for some reason and a gas giant with 60 moons has been spotted in the Goldilocks zone of a nearby solar system. They arrive there and it turns out, a space-fairing community has already developed.

Firstly, could a Jupiter-like planet form in the Goldilocks zone? Secondly, could a few of its moons be able to support life? Thirdly, could advanced, space-faring life evolve separately on at least 4 of the moons? Fourthly, would they be friendly to our earthlings? And finally, what might society and culture be like?

  • $\begingroup$ Hello and welcome to Worldbuilding @Gnorsk. Regarding points 4 and 5... if they are friendly or not, and what the society would be life, is entirely up to you as the author. 3 is kind of broad and up to you as well. For point 2: define "life". $\endgroup$ – MichaelK Jul 28 '16 at 8:54
  • $\begingroup$ For approachable information on what we’ve learned about the formation of planets and wnere they wind up, peruse the SETI Colloquium series. This is a common subject that is covered with current findings! $\endgroup$ – JDługosz Jul 28 '16 at 9:39

    $\begingroup$ I don't think you could have 60 moons in stable orbits around a single planet... $\endgroup$ – Annonymus Jul 28 '16 at 10:15

    $\begingroup$ @Annonymus tell that to Saturn. Moons do not have to be large and spherical. A bunch of 10km rocks could also constitute 60 moons. They won't be inhabitable, but that was not the question. $\endgroup$ – Chieron Jul 28 '16 at 13:29
