Kerberos
Kerberos is a small natural satellite of Pluto. Kerberos orbits between Nix and Hydra and makes a complete orbit around Pluto roughly every 32.1 days. This 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). Like Pluto's other satellites, it is suspected that Kerberos coalesced from the debris of a massive collision between Pluto and another Kuiper belt object, similar to the giant impact thought to have created the Moon.
