Bryson reading chapter 2 QQC

Quote: "A few astronomers continue to think there may be a Planet X out there—a real whopper, perhaps as much as ten times the size of Jupiter, but so far out as to be invisible to us. (It would receive so little sunlight that it would have almost none to reflect.) The idea is that it wouldn’t be a conventional planet like Jupiter  or Saturn—it’s much too far away for that; we’re talking perhaps 4.5 trillion miles—but more like a sun that never quite made it. Most star systems in the cosmos are binary (double-starred), which makes our solitary sun a slight oddity."

Comment: I think the idea of a vary large planet is interesting and very possible, but until proof is found, I remain skeptical towards the matter. I do find it interesting that most star systems consist of pairs of stars (i.e. two suns) while ours is unary consisting of individual stars (i.e. one sun).

Question: How do the binary star systems affect the solar system in comparison to unary star systems? Do they affect things like shape, gravity, orbit, and other aspects? How are these aspects affected?
