With an orbit that takes 200,000 years, it's fairly safe to see it has never been seen by human eyes before, but does it mean it hasn't created havoc at other times? If it does exist, could it have been responsible in some way for any of the mass extinctions scenarios? Could its gravitational force have pulled asteroids out of orbit from the asteroid belt between Mars and Jupiter, or the Kuiper Belt at the edge of our solar system, and caused them to strike the earth? I'm sure there are other possibilities as well, so it will give us a lot to think about if it is truly out there.
