    Notes:
    1. Reference: Wikipedia: Dwarf Planet: Population of dwarf planets. These are the most notable dwarf planets as of 2022. But there are many other candidate dwarf planets (see Wikipedia: Dwarf Planet: Most likely dwarf planets; Wikipedia: List of possible dwarf planets. In fact, the category dwarf planet may NOT be useful since it is so hard to decide what small Solar System bodies (SSSBs) are dwarf planets.
