    Be funny if we share an orbit with another Earth that is exactly in sync to stay behind the sun.

      That would be quite a surprising find indeed. I’m pretty sure that we would have already observed the gravitational effects of such a planet though. The Planet X and Planet Y the article refers to are out on the fringes of the solar system with Pluto, which is still pretty neat I think.
