We all die! :-) Okay, it's cool looking. But nothing will live up to the two stars in Star Wars. :-) Though, I don't know the feasibility of the science on that one.

Our neighborhood has a triple-star system!

That's a triple-planet system. Presumably millerm's asking about stable-orbit, habitable-zone planets in a multiple-star system, like Kepler 47: http://news.nationalgeographic.com/news/2012/08/120829-new-p...

Nope, the system mentioned here [1] is a triple-star system. Read the first line [2].

two star systems are more common than a single star system in the universe.

There are systems with twin stars.

But how stable would a planet's orbit be in a two-star system?

http://en.wikipedia.org/wiki/Twin_star_system#Planets says »Simulations have shown that the presence of a binary companion can actually improve the rate of planet formation within stable orbital zones«
