Abstract

With the class of “dwarf planet,” we come face-to-face with the heated public and scientific controversy that followed the 2006 decision by the International Astronomical Union (IAU) to “demote” Pluto and create this new class of objects. It was one of the most notorious decisions in the history of the IAU and in astronomical classification. The decision might not have been so controversial if a dwarf planet were ruled to be a type of planet; however, it was ruled instead to be a subplanetary object. We classify it here following those decisions.
