Trinary Stars

<p>Trinary Star System? Someone please tell me how big one of these would have to be? And would exploring one of them be a good campain/adventure hook. Will you find the Twelve Colonies of Kobol in such a system or a bunch of gas giants and useless dusty rocks? Would I develope wrinkles faster with all these Extra UV rays? LOL Has anyone made any hard rules about designing such a system?</p>
