Nibiru or Planet X Rersearch?

If any of you watched that video about possible flyby scenarios! know one thing, Nibiru is a self navigating planet! possibly with its own satelites and other junk that gets caught up in its gravitational field! So its almost like its own constellation! So if you can try to imagine, the amount of disturbance or havoc it can cause if it gets really close to our planet, hell our solar system! fanthom that!
