Lots of luck proving it, but at least it sounds more plausible than the notion of a dark star we couldn't detect as a binary partner of our Sun. It's nice to see this more reasonable theory.

The odds are pretty good that there is one maybe even two other large nearly Jupiter size objects in the area from the Kuiper belt to the the Oort Cloud or the Theoretical Oort Cloud.

Consider if they are right about the planetary migration that took the outer planets to their current position then likely their are other planets that started off closer to the sun but moved further away. The resonace of the Jupiter and Saturn orbit may have not only have pushed Neptune and Uranus further out but also other planets into far more elliptical course into the outer solar system. That course could change over the millennium to push it's closes pass to the sun beyond pluto where and may explain Pluto origin as a Neputnian moon.
