Do you think Pluto should be removed from the category "Planets" on the ground that it is no longer officially a planet? In that case Pluto should be moved to a new category "Dwarf planets" (possibly "Trans-Neptunian objects". Keeping it in the category "Planets" could be justified on the grounds that in 1991-1998, Pluto was still a planet, at least to Muggles. Hmm, is Wizard knowledge of astronomy ahead of, behind, or about the same as that of Muggles? Might the Wizards have already demoted ("plutoed") Pluto by 1998? Btw, if it is decided to create an article on Sedna, Orcus, Quaoar, or any other trans-Neptunian object that is in all likelihood a dwarf planet but has not been formally declared to be such, feel free to place it in the category "Dwarf planets" nonetheless.

I am fascinated with trans-Neptunian objects.Hallj36 11:04, February 20, 2012 (UTC)

Should remain as is, since it was never changed from being a planet in canon. The background information regarding this matter is already covered in "behind the scenes." ProfessorTofty 14:13, February 20, 2012 (UTC)
