My personal theory is that there are a lot of free roaming planetary bodies in space that we don’t know about and they occasionally get captured as they pass a star.

I don’t know why it should be a surprise that some planets orbit their stars in the opposite direction.
To me, it’s rather silly to extrapolate all solar system observations to the entire universe, when there is a total of n=1 systems being observed. A workable hypothesis really cannot be developed on a basis of n=1.

Which reminds me of a question: If you add up all the angular momentum of all the planets around the sun and that of the sun itself, that's a huge amount of energy. Where did it come from?
And why is it all in the same direction? It seems things falling into the sun's gravitational well would randomize in their contribution of potential energy to angular momentum. Instead, it all adds up in the same direction...

Will any be transiting our solar system anytime soon?

Thanks decimon!
When these new results were combined with earlier observations of transiting exoplanets astronomers were surprised to find that six out of a larger sample of 27 were found to be orbiting in the opposite direction to the rotation of their host star -- the exact reverse of what is seen in our own solar system.
I guess no one there got the memo that the KBOs found so far have been on wacky orbits, suggesting they were hurled out by interaction(s) with other bodies -- and for that matter, that most of the planet Jupiter's 60+ known moons orbit in retrograde, a status often considered diagnostic of capture. The so-far unknown outer planets of our own system will be found to be moving in retrograde.

Thanks decimon! A two-list ping!
