Our guests today have written a paper outlining efforts to locate this planet using WISE and NEOWISE data. They think that Planet Nine, if it exists, should be self-luminous enough and potentially bright enough in the near infrared that the NEOWISE telescope should be able to see it. Today we’ll talk about those efforts along with what WISE and NEOWISE is, why we think Planet Nine is there in the first place, and whether or not it will have any adverse effect on the Earth anytime soon.
