Pluto & Charon 9th or Dwarf Planet Solar System Key Ring

Pluto and its largest moon, Charon, are an intriguing duo in the far reaches of our solar system. Nicknamed a "double dwarf planet system" because of Charon's unusual size relative to Pluto (nearly half its diameter), they are locked in a cosmic dance where they eternally face each other, creating a mesmerising slow ballet in the Kuiper Belt. - This file is in the public domain in the United States because it was solely created by NASA.
