The contest ends today at noon for the naming of the two moons of Pluto, discovered in the last two years.

Sponsored by SETI, a not-for-profit organization whose mission is to “explore, understand and explain the origin, nature and prevalence of life in the universe,” the contest has been collecting nominations for names for the newly discovered moons, currently known as P4 and P5, since mid February.

With over 150,000 individual votes, Vulcan is the clear frontrunner in this eleventh hour. And if popularity rules the day, the other moon will ne dubbed is Cerberus, which according to Greek mythology, is a three-headed hound.

While Vulcan is well-known as the logical species on Star Trek, it actually is a mythological figure–the Roman god of fire.
