Pluto was only discovered in the 1930s. The only cultural heritage of Pluto as a ‘planet’ is a few decades of science schoolbooks, but going by these comments you'd think it's been in the same list as Jupiter since the Babylonians.
Uranus and Neptune don't have a long human heritage either. Neither appears to have been known to the Babylonians.
