In the extinct Polabian Slavic language, it was "perundan", Perun being the Slavic equivalent of Thor. There

Since the orbits of these objects are entirely dictated by Neptune's gravity, Neptune is therefore gravitationally dominant. On June 11, 2008, the IAU announced that the subcategory of dwarf planets with trans-Neptunian orbits would be known as "plutoids". In an accompanying press release, the IAU said that: This subcategory includes Pluto, Haumea, Makemake and Eris. Some aspects of the definition are as yet difficult to apply outside the Solar System. Techniques for identifying extrasolar objects generally cannot determine whether an object has "cleared its orbit", except indirectly via an
