Styx is a small natural satellite of Pluto whose discovery was announced on 11 July 2012. It was discovered by use of the Hubble Space Telescope , and is the smallest of the five known moons of Pluto .
Pluto's four small circumbinary moons orbit Pluto at two to four times the distance of Charon, ranging from Styx at 42,700 kilometres to Hydra at 64,800 kilometres from the barycenter of the system. They have nearly circular prograde orbits in the same orbital plane as Charon. All are much smaller than Charon.
Nix is the third moon of Pluto by distance, orbiting between the moons Styx and Kerberos. [11] Nix was imaged along with Pluto and its other moons by the New Horizons spacecraft as it flew by the Pluto system in July 2015. [12] These images reveal a large reddish area on Nix that is likely an impact crater. [13]

Pluto likely acquired large moon Charon in a “kiss and capture” collision billions of years ago. It may have created a subsurface ocean on the icy dwarf planet.
Kerberos is a small natural satellite of Pluto, about 19 km (12 mi) in its longest dimension.Kerberos is also the second-smallest moon of Pluto, after Styx.It was the fourth moon of Pluto to be discovered and its existence was announced on 20 July 2011. [1]
