And not crappy old Pluto.... www.theregister.com/2020/12/11/planet_nine_hubble/The Hubble Space Telescope has spied a previously unknown exoplanet with similar properties as our Solar System's hypothetical object Planet Nine. This newly spotted body is living on the outskirts of another solar system 336 light-years away. Astronomers have not yet glimpsed Planet Nine after it was predicted that the massive body may be orbiting our Sun on the outer edges of our Solar System. The evidence for such a planet could explain why the orbits of some distant Kuiper Belt objects beyond Neptune were so strange. New readings from the Hubble Space Telescope point to just such a body orbiting a star 336 light years away. An exoplanet, dubbed HD 106906 b, has been tracked by a team of researchers led by those at the University of California, Berkeley, who analysed images taken over a 14-year period of the exoplanet to estimate its orbit.

"it was predicted that the massive body may be orbiting our Sun"
"just such a body orbiting a star 336 light years away"
I don't get it - which one is it orbiting?

"it was predicted that the massive body may be orbiting our Sun" "just such a body orbiting a star 336 light years away" I don't get it - which one is it orbiting? Yeah, didn't notice that. Could it be a smaller star I wonder and both are in orbit around the sun incredibly slowly. Most solar systems have more than one star after all.

Maybe it is correct in that it was initially predicted to orbit us but was then found out there orbiting another star. Difficult to see how you mistake the gravitational impact of one with the other, though, as the two scenarios represent vastly different physical angular ranges.
