I’ve heard about this a few times recently, at first I chalked it up to the old, but viral “Planet X or Planet 9 discovered” hoax that’s been made on multiple occasions, but there’s a variety of recent articles pointing to the possibility. I am aware that such news brings a lot of trafic (so money) to news outlets, so I was wondering if this was simple sensationalist news or something we’re actually proposing again?
I definitely remember learning about how unlikely it was for a **real** planet beyond the orbit of Neptune to exist. (Fairly) Modern calculations and observations were also pointing towards it not even being a possibility.
So what changed in the last year? What have we learnt, observed, discovered, calculated, etc.? Is this misinformation or an actual old scientific hypothesis that’s being reinvestigated again in light of recent and new data?
(Possibly used the wrong flair, but it kinda made sense.)
In: Physics
“Planet 9” has been proposed as a way to explain the orbital behavior of certain objects outside the orbit of Neptune. Such a planet has not been actually observed, and there are alternate explanations for the observed behavior of objects.
