Dwarf planets - size reference

Well-known member
I decided to post a list of dwarf planets ordered by size, to bring some perspective. I will list all astrological relevant objects, (that is, no moons of other planets), from Mercury down to Ceres in size order, and select smaller than Ceres objects.

All sizes are mean radius, source Wikipedia.

  • 2439.7 - Mercury
  • 1737.1 - Moon
  • 1300 - Eris
  • 1195 - Pluto

  • 600 - 2007 OR10 "Snow White"
  • 575 - Haumea

  • 525 - 2005 QU182
  • 500 - Quaoar
