Acheron, Alecto, Cerberus, Erebus, Eurydice, Heracles, Hypnos, Lethe, Obolus, Orpheus, Persephone, Styx and Vulcan. These are the thirteen names that the SETI Institute is currently considering to name the new moons of Pluto found in 2011 and 2012 thanks to the Hubble Space Telescope.
They have temporarily been called "P4" (diameter from 13 to 34 kilometers) and "P5" (diameter from 32 to 113 kilometers), but now they have left the decision to choose their final name in the hands of Internet users. Online voting will last two weeks and will end on February 25. Afterwards, the names of the moons must be approved by the International Astronomical Union (IAU). If you want to participate and help in the baptism, you can do it here.
By tradition, the names of Pluto's moons come from Greek and Roman mythology, and are related to ancient tales about Hades and the underworld.
