Pluto
Pluto as observed by the New Horizons spacecraft, July 13, 2015.
The largest moon of the dwarf planet Pluto is Charon.123
Charon is significantly larger than Pluto’s four other known moons—Hydra, Nix, Kerberos, and Styx—measuring approximately 1,212 km in diameter, which is fully half the size of Pluto itself. Due to its substantial size and mass relative to Pluto, the two bodies are sometimes considered a double system.1234
