Double Worlds

pluto and charon

Pluto may be demoted from planethood, but I still call it a world. Its major moon Charon is large enough to tug significantly on the pinkish body. Technically, both Pluto and Charon orbit an empty space some miles above the surface of Pluto. If these were planets, they would fit the definition of a double planet.
