Pluto may have been demoted, but its family is getting bigger and bigger. Now, two of the dwarf planet’s tiniest moons need names — but rather than leaving the Plutonian satellites’ naming ceremony to astronomers, that honor has fallen to you.
The discoverers of Pluto’s smallest moons — measuring only 15 to 20 miles across — have designated the moons “P4? and “P5,” but it’s about time that they grow up and get some real names. Discovered in 2011 and 2012 by the Hubble Space Telescope, this tiny duo joins Charon, Nix and Hydra in a very close-knit family of objects orbiting Pluto.
All of the objects were named after Hades and the underworld inpluto rocks ancient Greek mythology. Hades, god of the underworld, who was also known as “Plouton” (meaning “Rich One”), was Latinized by the Romans to, simply, Pluto. And the ninth planetary body from the sun was given that name by 11-year old schoolgirl Venetia Burney shortly after the small world was discovered by Clyde Tombaugh at Lowell Observatory in 1930. The mythological name for the dark and cold world on the outskirts of the solar system has now been inherited by Pluto’s satellites.
So, the SETI Institute has launched a new website called “Pluto Rocks”
to decide new names for P4 and P5. Of the possible mythological names, the following can be selected: Acheron, Alecto,Cerberus, Erebus, Eurydice, Hercules, Hypnos, Lethe, Obol, Orpheus, Persephone and Styx. You can also make your own suggestions.
