Portrait of Pluto and its binary companion Charon, composed from two images taken by NASA’s New Horizons spacecraft in July 2015.
Charon is the largest of Pluto’s five moons and, at half Pluto’s size, is the largest known satellite relative to its parent body.
Pluto and Charon are mutually tidally locked, meaning the same hemispheres of both bodies always face each other.
Charon orbits Pluto every 6.4 Earth days.
