Scientists examining data from NASA's Hubble Space Telescope have spotted a fifth moon orbiting Pluto. The moon is currently labeled?S/2012 (134340) 1, a monicker that could probably be improved.?
This 2006 image from NASA's Hubble Space Telescope shows Pluto and three of it's moons. A team of scientists using the telescope said Wednesday that they have discovered the tiniest moon yet around Pluto. That brings the number of known moons to five.

This newest member of the solar community currently goes by the unprepossessing label "S/2012 (134340) 1." Clearly, it's in desperate need of a name. What will astronomers christen it?
It can't be named just anything under the sun. As usual with newly discovered astronomical objects, S/2012 (134340) 1's name will be subject to a tough selection process overseen by an organization called the International Astronomical Union. IAU guidelines specify that "objects crossing or?approaching the orbit of Neptune?? notably [Pluto and its moons], are given mythological names associated with the underworld."
Pluto was the god of the underworld in Roman mythology. Charon, the largest of?Pluto's moons, is named after the mythical ferryman who carried the souls of the newly deceased across the River Styx, which separated the world of the living from that of the dead. Nix, Pluto's second-closest moon, was the Greek goddess of darkness and night, and Charon's mother. Hydra, the third closest to Pluto, was a many-headed serpent that guarded a back entrance to the underworld located deep below the surface of a lake. [Why Doesn't Earth's Moon Have a Name?]
The dwarf planet's fifth moon needs a name along these hellish lines, and so does its unnamed fourth moon, which was provisionally designated P4 at the time of its discovery last July. The IAU nomenclature committee will try to honor the wishes of the two moons' discovery team, which includes Alan Stern, a planetary scientist at the Southwest Research Institute in Boulder, Colo.
So, what's his choice? "There are dozens of ideas but nothing is close to settled," Stern told Life's Little Mysteries. He said he prefers to defer the decision until his team finishes mining the Hubble data in search of additional moons orbiting?Pluto.
"When we discovered P4, I was on the side of advocating waiting to see if we discovered more moons and then naming them as a group, like we did with Nix and Hydra," Stern said.
If no more moons are spotted, then the two new foundlings will likely be named for an "underworldly" mythological duo. Know any?
