I always enjoyed the romanticism of a world with two suns or multiple moons. But that's when I start thinking a little too much, and I come up with more questions than anything.Multiple moons. Anyone have any idea what it would do to a planet to have, say, two moons? It of course depends on each moon's orbital pattern, but just think what that would do to the tides, among other things.Multiple suns. This gets even more hairy. I can't remember the terminology from my college astronomy days, but a planet can have different patterns in a binary star system (if it's even possible to have a planet in one). But I imagine having two suns for a planet could really screw with the environment as we know it.It's always bugged me when a stories/movies/etc. have multiple moons and suns without considering these things. Though maybe I'm just being weird. I know Tattooine has two suns, but all Lucas came up with was that it was a desert planet (which may be all there is to it). Honestly, I'm more interested in ideas with multiple moons.Anyway, there's probably a brainiac or two out there who knows a lot about this stuff. If you're bored, please give me your thoughts on how a fantasy planet would be altered to fits either option.</blockquote>
