Plato vs. Pluto, rather with style of pluto staying in your own orbit, loving from a distance, than with Platonic style, too much greasy.

"Pluto has five known moons: Charon (the largest, with a diameter just over half that of Pluto), Styx, Nix, Kerberos, and Hydra.[21] Pluto and Charon are sometimes considered a binary system because the barycenter of their orbits does not lie within either body.[22] The IAU has not formalized a definition for binary dwarf planets, and Charon is officially classified as a moon of Pluto.[23]"
