Five Dwarfs

Dwarf PlanetsA dwarf planet is a planetary-mass object that isn’t a planet nor a natural satellite of a planet. It is in direct orbit around the Sun, and it is massive enough for its shape to pulled into a sphere by its own gravity. However, unlike all of the major planets, it has not cleared the neighborhood around its orbit.

The International Astronomical Union (IAU) currently recognizes five dwarf planets: Ceres, Pluto,  Makemake, Eris, and Haumea. They’re pictured above (from top left):

  1. I’m offended by your offensive use of the offensive term “dwarf.” You should get with the times and refer to these “Stellar” objects as “little planets.” 🙂

    How about Boomy? He too busy filing motions to dismiss motions to dismiss? Aka his Hegelian downward spiral of law fare.
