Pluto and Charon are double planets. Change my mind.
Pluto is smaller than Earth's moon. Should our moon be a planet too?

Charon is massive enough relative to Pluto that the former does not directly orbit the latter, but instead they both orbit a common barycenter located between them, making them a binary planetary system.
