User:DN-boards1/On binary dwarf planets

Essentially, in addition to the standard dwarf planets, the following moons are in hydrostatic equilibrium and exert a gravitational influence over their parent dwarf planet that forces them into a "binary dwarf planet" relationship rather than a "dwarf planet-moon" relationship:


 * Charon
 * Dysnomia
 * Hiʻiaka
 * Vanth

These are considered "binary dwarf planets".
