Image shows a sliver of Pluto’s largest moon, Charon, and all four of Pluto’s small moons, as resolved by New Horizons spacecraft. Charon has a diameter of 751 miles (1,212 kilometers). Nix & Hydra have comparable sizes, approximately 25 miles (40 kilometers) across in their longest dimension above. Kerberos and Styx are much smaller and have comparable sizes, roughly 6-7 miles (10-12 kilometers) across in their longest dimension. All four small moons have highly elongated shapes, a characteristic thought to be typical of small bodies in the Kuiper Belt.
