The way I look at it, we didn’t lose a planet. We gained several others as dwarf planets. Dwarf planets are still planets after all. Pluto is their king. And if there’s one thing we should have all learned by now it’s that you don’t mess with dwarf kings.
At least half of the reason is that 2012 was roughly when a lot of millennials graduated from highschool and had to get jobs and pay bills and shit.
and charon, which is in mutual orbit with pluto and not that much smaller
which really shows how much the average “pluto is a planet” person actually knows about space, lol
And my mates Ceres and Sedna! And Orcus, Makemake, Haumea, Eris (which started this whole deal), Gonggong, Quaoar, Salacia, Leleākūhonua, and at least 40 undiscovered Sednoids. Vesta, Pallas, Hygeia, and Interamnia probably counted at one point too!
At some point it stops being gatekeeping and is just another kingdom entirely.
Nasa?
Pluto never changed; we did.
