Pluto Moons: Smallest in Orbit Receive Names of Styx and Kerberos

Just in case you hadn't heard, here's the latest news for your space forecast. Two tiny moons orbiting the dwarf planet Pluto just got their names: Styx and Kerberos.

According to the International Astronomical Union-the organization responsible for naming celestial objects-these two guys were previously called P4 and P5, but an internet poll showed that they needed a new title. 

The new names were allegedly based off the Pluto Rocks Internet poll, sponsored by SETI (the Search for Extraterrestrial Intelligence).

Despite that the name Vulcan led in the polls as a name for one of the moons, along with Cerberus, neither got the glory.

Specifically for Vulcan, experts say this name couldn't be used as it was the name of a hypothetical planet between Mercury and the Sun. (What?) And though the planet was found to be non-existent, asteroids orbiting within the same realm are called 'vulcanoids.' 

The moon Kerberos floats between two other larger moons named Nix and Hydra that were previously discovered in 2005, and Styx is stuck between Charon, the biggest and closest moon, and the other, Nix. Kerberos is also believed to be between eight and 21 miles in diameter. Styx, on the other hand, is thought to be much smaller, at only six and 15 miles and in a rather irregular shape.

Both of these moons have a circular orbit.

Are you happy with the names?
