Despite the rules, NewScientistSpace.com readers managed to come up with some fairly outrageous appellations. The Web site asked readers to weigh in on August 2.
Writer and editor Sean O'Neill headed up the informal survey. "The response was huge," he wrote in an e-mail to National Geographic News. "We received about 1,500 e-mails, and the vast majority were really well thought out, considered responses."
The clear winner was "Persephone" (Greek spelling) or "Proserpina" (Roman).
In Greco-Roman mythology, Pluto/Hades, god of the underworld, kidnapped Persephone/Prosperina and made her his wife. Her mother's sadness was such that it caused wintermaking the name especially apt for a cold, distant planet.
What's more, Persephone spent only half her time in the underworlda nice twist, says Brown, the Caltech astronomer. UB313's very oblong orbit brings it close to Pluto during only half of the time.
Brown too has received "a ton" of name suggestions via e-mail, and they've been "overwhelmingly" for "Persephone/Proserpina."
The fan favorite, though, may be thrown out on a technicality. The IAU forbids a name to be used twice, and Persephone has already been assigned to an asteroid.
"But there's always a chance that the IAU will say, We don't care about that stupid asteroid," Brown said.
Brown pronounced the runner-up"Peace," or its Latin root, "Pax""a good name." And according to O'Neill, of NewScientistSpace.com, Brown "really liked [sixth-ranked] 'Bob' as a possible name."
"Galileo," "Xena," "Rupert" (after a gag in The Hitchhiker's Guide to the Galaxy), "Titan," "Nibiru," "Cerberus," and "Loki" round out the NewScientistSpace.com readers' top ten.
As for nutty names, "Bob" was only the beginning. "After Pluto, there were lots of other cartoon dogs suggested, and 'Mickey Mouse' and 'Scooby' both did quite well," O'Neill said.
A few suggestions were, like UB313, firmly on the fringes. "'Spongerock Roundplanet' was never going to make the cut, for example" O'Neill said, "and neither was 'Mianus.'"
Back to the Drawing Board
As of yesterday, you and I know as much about 2003 UB313's name as the planetoid's discoverer does.
Brown's suggested name was made under the guidelines for naming a small body, which don't specify a preferred cultural origin.
"But I just heard from the IAU that, if they rule that it's a planet, they want to go with a Greco-Roman name [along the lines of 'Saturn,' 'Jupiter,' and 'Mars']," Brown said, "which is not at all what I suggested."
