[QUOTE="Aesmael, post: 1742860, member: 22503"] First, by what you've said so far, sounds like having the jovians where/as they are and habitable is part of the campaign. You don't want help turning Jupiter into a realistic life source, right? So: The moons will always have the same face pointed Lucifer's way unless people have expended effort to make them rotate. This will not necessarily make them uninhabitable - there was a recent paper which found that planets orbiting stars in this manner would not end 'fire and ice' (hearsay from me, I have not been able to track it down to read yet). Unless you take Lord Satan's suggestion (I'm tempted to recommend it, just so I can say I did) and move them out from their current positions the years will be very short. The current range is from 1.7 days for Io to ~16 for Callisto. Not necessary to move them though, if you are just handwaving the illumination, but remember that Lucifer will not be as bright. Unless you want to go into math just say it is bright (that's in regards to Mars and Terra, I assume you know how you want it to look from them) :p Consider that most of the jovian moons are in resonant orbits with each other. Europa, for example, is in the same position in Io's sky every two (Io) orbits. You might want to play up the regularity of their skies if you go for that. Is this intended to be an adaption of our solar system, or just a similar setup to the Odyssey stories you mentioned? (curiosity) Pbartender, although those planets seem to be very common, it is unlikely they would have habitable moons. Satellites tend to get stripped off them when they orbit that close. Which does not mean you can't set it up that way, but it would probably be a temporary situation and any inhabitants more likely arrived from elsewhere than evolving on site. Interesting book, will check it out. Had considered writing something similar, but not yet qualified.:lol: Lord Satan, student or? [/QUOTE]
