minus-square@[email protected]linkfedilinkEnglish1•25 days ago The problem with recognizing Pluto is that Eris, Haumea, Makemake, Gonggong, Quaoar, Sedna, Ceres, Orcus, and perhaps also Salacia also should probably be included If one uses diameter as the cutoff, then Pluto is larger than all of those.
minus-squareEnkrodlinkfedilink7•25 days agoNah, the cutoff is “is it mostly spherical due to its own gravity?” and “has it cleared its orbit from other bodies?” Pluto is massive enough to be spherical but did not clear its orbit from other bodies. Now its the head of its own family, the dwarf-planets.
minus-square@[email protected]linkfedilink3•25 days agoIndeed, but Eris is only marginally smaller and a fair bit more massive, and the latter is generally more important in categorization.
