The three-body problem, scientists' term for figuring out the orbital quirks of a planet circling not one star but two, is so tricky that its name has inspired an award-winning novel. But the three-body problem is a piece of cake compared to the next degree of complexity—how a planet interacts with three stars at once.

It turns out that situation isn't quite as chaotic as might have been expected, according to new research presented at the annual conference of the American Astronomical Society held this week in Denver, Colorado.
