Kerberos is a small natural satellite of the planet Pluto.
On June 28, 2011 Mark Showalter discovered the moon, and on July 20, 2011 his finding was published.
- It was named after Cerberus, a dog in Greek mythology.
- Kerberos was formerly known as S/ 2011 P1, or simply P4.
- The name was going to be called Cerberus but there was already an asteroid called that.
- In 2013, a vote was held to name the two new moons of Pluto. The winner was Vulcan, but Vulcan was already the name of a fake planet between Mercury and the sun, so the second and third names were chosen.
- In addition to the name Vulcan already in use, it didn't relate to the underworld theme that Pluto and its moons all follow.
- The name Vulcan was suggested by William Shatner, the actor that plays Captian Kirk in Star Trek, because it was the name of a planet in Star Trek. He also suggested Romulus, but it was discarded as an asteroid was already named that.
- Kerberos orbits Pluto every 32 days.
- It was discovered about a year before Styx.
- Kerberos is between 13 and 32 km in diameter.
- It is the second smallest moon of Pluto, next to Styx.
