What would happen if the material making the various objects orbiting our sun was all reshuffled? In this new arrangement, Earth would be more-or-less unchanged, but it would now be a moon of a gas giant. In addition, all the other planets and moons (along with the asteroids and comets) would now be making up a Earth-like moons as well. How many gas giants could fit into the Goldilocks Zone, and how many moons would there be?
