Charon (Sol 9a) is a moon of [Pluto (Sol IX)](https://robertsspaceindustries.com/galactapedia/article/0qa1Zo37jk-pluto-sol-ix), [United Empire of Earth](https://robertsspaceindustries.com/galactapedia/article/VyvyKxy4v6-united-empire-of-earth) (UEE).

The two bodies are thought by astrophysicists to have collided in their formation before settling into their current orbit.
