Notes

edit
  1. ^ Though astronomers generally accept Orcus as a dwarf planet, some doubt remains
  2. ^ a b c A major moon is a moon that is hydrostatically round.
  3. ^ Mass calculated using Vanth's estimated mass
  4. ^ As the transition from atmosphere to other is unclear for the giant planets, they are not included in this
