Brown et al aren&#x27;t, to my knowledge, simply hoping this hypothetical planet into existence a la Nibiru. Brown discovered Eris and his handle on Twitter is @plutokiller for a reason. See https://arxiv.org/abs/1603.05712 for previous work. Edit: Adding from the Conclusion The existence of a distant massive perturber in the outer solar system – Planet Nine – explains several hitherto unconnected observations about the outer solar system, including the orbital alignment of the most distant Kuiper belt objects, the existence and…</p><p><a href="https://hackerpaper.kaipfister.de/p/1603.05712/">Paper and discussion history</a>.
