Want to name Pluto's two tiniest moons? Then you'll need to dig deep into mythology.

Astronomers are asking for the public's help to rename "P4" and "P5, which were found by the Hubble Space Telescope in 2011 and 2012.

Voters can choose between several names associated Greek and Roman mythology: Acheron, Alecto, Cerberus, Erebus, Eurydice, Hercules, Hypnos, Lethe, Obol, Orpheus, Persephone, and Styx.

Three of Pluto's moons already have names relating to the ancient tales about Hades and the Underworld. They are Charon (KEHR-on), the ferryman of Hades; the half-human, half-fish spirit Nix; and the multi-headed monster Hydra.

The two tiny moons are no more than 24km to 32km across.

Votes can be cast online here. Write-in suggestions are welcomed, however the final decision lies with the International Astronomical Union.
