Kerberos

Kerberos is a small satellite of the dwarf planet Pluto. It was discovered by the Pluto Companion Search Team when using the Hubble Space Telescope on June 28, 2011.
moon of Pluto after Styx and measures 19km at it's longest dimension.
== Origin ==
It has been suspected that Kerberos was formed from an impact that could have likely formed the other moons as well. This theory is similar to the one that created the moon.
== Physical Characteristics ==
Kerberos appears to be double-lobed in shape, and is approximately 19 km (12 mi) across its longest dimension and 9 km (5.6 mi) across its shortest dimension. It is the second-smallest of Pluto's moons, after Styx. The larger lobe of Kerberos is approximately 8 km (5 mi) across while the smaller lobe is measured to be approximately 5 km (3.1 mi) across. The double-lobed shape of Kerberos is likely formed by two smaller objects merged, suggesting that Kerberos along with Pluto's other moons may have been formed by the coalescence of debris around Pluto.
Kerberos has a very high albedo, consistant with that of ice water.
=== Rotation ===
Like the other moons of Pluto, Kerberos is tidaly locked in place, although it rotates very choaticly, spinning end over end.
== Orbit ==
Kerberos's orbit is very circular and not inclined. It has an equatorial orbit around the Pluto-Charon barycenter, 
with an average distance of 57,783 km. All of Pluto's moons including Kerberos have very circular orbits with very low orbital inclinations to Pluto's equator. Kerberos orbits between Nix and Hydra and makes a complete orbit around Pluto roughly every 32.167 days.
Its orbital period is close to a 1:5 orbital resonance with Charon, with the timing discrepancy being about 0.7%. As with the near resonances between Nix or Hydra and Charon (1:4 and 1:6, respectively), determining how close this relationship is to a true resonance will require more-accurate knowledge of Kerberos's orbit, in particular its rate of precession.
