What Would It Be Like to Live in a Moon of Another Planet?

Billy asks: What would it be like to live on a moon of another planet? It's a really fun question especially for example if you're writing a science fiction novel that's set on one of those planets as I suspect Billy might be. You think Billy just has an old terrier motive here? Can't you be asking out of sheer curiosity? Absolutely. But after we give our answer he'll be well set up to write that novel and I'm looking forward to reading it. The hymn and tens of thousands of people very good typing fast Billy. Thank you, Billy.
