As we get farther away from the sun the Planets tend to have more moons. Pluto has a total of five moon. They’re names are Charon, Nix, Hydra, P4, and P5.
Charon is the largest moon of Pluto. Charon was discovered in 1978. Charon’s diameter is about 1,207 kilometers and its about half that of Pluto, with a surface area of 4,580,000 square kilometers  However unlike Pluto, which is covered with nitrogen and methane ices, the surface of Charon appears to have less water ice, and also appears to have no atmosphere. Charon contains less rock than its partner Pluto. The two objects are in a synchronous orbit meaning they keep the same face towards the other during rotation. Pluto and Charon have been called twin planets because they are so close to each other in size. It takes 6.3 days for Charon to make one revolution around Pluto. Nix is the second moon that orbits Pluto. Nix’s size hasn’t been accurately measured but it’s estimated that it has a diameter between 46 km and 137 km. Nix’s orbital period is 24.86 days. Hydra is the third moon that orbits Pluto. Hydra and Nix were discovered at the same time in 2005. Hydra’s diameter has been estimated to be between 61 km and 167 km. Hydra is brighter than Nix. Hydra is farther away then Nix so it’s orbital period is 38.21 days. P4 is the fourth moon that orbits Pluto. P4 was discovered in 2011. P4 has a diameter between 13–34 kilometers. P4 has an orbital period of 32.1 days. P5 is the last moon of Pluto. P5 was discovered this year in July. P5 has a diameter between 10 and 25 kilometers. P5’s orbital period is 20.2 days. According to NASA, all of Pluto’s moons may have been formed from collisions of debris in space, kinda like how the Earth’s moon was created.
