The real story[edit]
... can be found here. (Slightly more plausible than many such claims.) 82.44.143.26 (talk) 16:45, 3 May 2018 (UTC)
Another planetary hype magnet[edit]
Can be found here. Anna Livia (talk) 20:23, 5 August 2018 (UTC) Perhaps there could be a little (funspace) list:
Will add Ultima Thule [1] to the above.
Perhaps there could be 'a little list' of all actually existing things which are not Planet X, including 'Oumuamua and the Voyagers and the heliopause [2], to keep track of such possible subjects of claims. Anna Livia (talk) 23:48, 30 December 2018 (UTC)
Will add [3] to the list; [4] will serve for Ultima Thule Anna Livia (talk) 16:32, 4 September 2023 (UTC)
What about this?[edit]
https://bit.ly/whatsbeyondNeptune
The source for the "dead star" is likely Tom Van Flandern in "Does Our Sun Have a Dark Companion?" (Newsweek, 28 June 1982). He estimates it to be a black hole or neutron star, which cannot be detected (and hence ruled out) by WISE due to emitting mostly X-rays and gamma rays. The source for the "tenth planet" is unknown.

- I'm not entirely sure what that picture is trying to say, but anything emitting mostly X-rays and gamma rays would also be emitting a lot of infrared radiation. WISE failed to detect a lot of stuff in the Kuiper Belt because it was too cold, not too hot. EyeSky (talk) 20:20, 26 April 2021 (UTC)
- But hot objects, like a neutron star, are supposed to emit far more X-rays and gamma rays than infrared radiation, which is probably why WISE (which detects infrared) missed the dead star. And Kuiper Belt objects are too small in surface area. It's also possible that the tenth planet is Eris, but Eris would have been in a different position (Cetus) than predicted by the image (~Taurus/Gemini). I prefer those hypothetical bodies over Planet Nine, and want to name the tenth planet Rupert and the dead star Danny. Joseph D. Pelobello/Daniel William "Danny" Willson 06:38, 2 May 2021 (UTC)
- They will emit more high energy radiation, but they will also emit more infrared radiation than colder objects, because they are approximate black bodies. If the high energy radiation were so intense as to interfere, the interference with WISE would be noted. See Planck’s law. EyeSky (talk) 13:57, 2 May 2021 (UTC)

X and Planet X[edit]
Anyone care to make a Planet X/X joke? Anna Livia (talk) 00:34, 27 January 2024 (UTC)
If we mean X as in Twitter, then no, because 1) I'm not calling it X, I still think that's stupid and 2) that'd be a disservice to astronomy, which is one of my favorite subjects. Sable! (talk) 13:59, 5 September 2024 (UTC)
