This Planet X / 9 business is certainly confusing. I hope the IAU soon come up with an official name for a possibly non-existent planet...
Seriously, you remember that group of anomalous orbits of some Trans-Neptunian Objects, which could be explained by the existence of Planet X? Turns out there's a possible alternative explanation - a disc of icy objects at 10 to 20 times the distance from the Sun as Pluto is. See Planet Nine might not actually be a planet
