Here are the moons of Pluto, in order of increasing distance from Pluto:

* Charon: The largest of Pluto's moons, and so large that it is sometimes considered a binary system with Pluto.

* Styx: A small, irregularly shaped moon.

* Nix: Another small, irregularly shaped moon.

* Kerberos: A small, irregularly shaped moon with an elongated shape.

* Hydra: The second-largest moon of Pluto, also irregularly shaped.

While Pluto itself has no rings, its largest moon, Charon, is thought to be surrounded by a faint ring of dust. This ring is theorized to be composed of dust kicked up by micrometeoroid impacts on Charon's surface.
