I was under the impression that the trajectories in question are referring to documented exo-planets, comets, and other space debris. He only
outlines 4 missions, Voyager I, II and the Pioneer series. We haven't sent that many satellites/craft on a course for deep space; at least that have
been made public.
That being said, I highly doubt that a private research company developing software would let graduate students, amongst others "in" on a huge secret
about an alleged planet that is responsible for mass chaos and destruction.
