The innermost and largest moon, Charon, was discovered by James Christy on 22 June 1978, nearly half a century after Pluto was discovered. This led to a substantial revision in estimates of Pluto's size, which had previously assumed that the observed mass and reflected light of the system were all attributable to Pluto alone.
With half the diameter and one-eighth the mass of Pluto, Charon is a very large moon in comparison to its parent body. Its gravitational influence is such that the barycenter of the Plutonian system lies outside Pluto, and the two bodies are tidally locked to each other. [ 19 ]
Webb for the first time detected carbon dioxide and hydrogen peroxide - both frozen as solids - on the surface of Charon, a spherical body about 750 miles (1,200 km) in diameter, researchers said ...

Simpler models from the early 2000s simulating how Pluto and Charon came to be in their current orientation supported the idea that some object collided with Pluto to create Charon.
Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius. These lists can be sorted according to an object's radius and mass and, for the most ...
The Pluto–Charon system is one of the few in the Solar System whose barycenter lies outside the primary body; the Patroclus–Menoetius system is a smaller example, and the Sun–Jupiter system is the only larger one. [151] The similarity in size of Charon and Pluto has prompted some astronomers to call it a double dwarf planet. [152]
