I consider the “Three Body Problem” as unrealistic. Such a system would be far too unstable for any kind of life to develop. Most likely, a planet in such a system ends up inside one of the suns, or thrown to outer space. And even if this system has a core of two suns orbiting each other, and the planet orbiting far outside in a halfway stable orbit, it would probably suffer from a kind of tidal effect by the suns, making it geologically … interesting.
