The closest known exoplanet is currently called Alpha Centauri Bb, but the folks behind Uwingu want you to come up with a cooler name.
"It might be Pandora. Who knows?" said planetary scientist Alan Stern, Uwingu's co-founder and chief executive officer.
As fans of the James Cameron sci-fi blockbuster "Avatar" know, Pandora is the name of the moon in the Alpha Centauri system where the movie's action takes place. In science fiction, planets beyond our solar system have colorful names. But in reality, exoplanets merely have designations that are based either on the name of the star they orbit (like Alpha Centauri Bb) or on the name of the probe that discovered the world (like?Kepler-37b)
The International Astronomical Union, which usually takes the lead role in naming celestial objects and features, has held back on creating an exoplanet-naming process. So Stern and his partners?set up Uwingu to fill the vacuum?? and make some money in the process.
Starting today, Uwingu is taking nominations for Alpha Centauri Bb's new name, at a price of $4.99 per suggestion. For 99 cents per vote, Uwingu's registered users can pick their favorite name. The name that has the most votes when the contest ends on April 15 will be crowned the people's choice. It won't carry any weight with the IAU, but Stern is hoping that the name will stick.
"There are people in the world who think astronomers own the sky, and what we're effectively saying is, it's the people who own the sky," Stern said.
The user who suggests the winning name will receive recognition and prizes from Uwingu. There'll be additional yet-to-be-specified prizes for runner-ups, and for those whose name suggestions reach the 100-, 1,000- and 10,000-vote level. Uwingu already has a list to start with, since it's been in the exoplanet-naming business for several months.
"Older names will be grandfathered in, but I think the new ones will soar past these," Stern told NBC News. (The current top vote-getter is Heinlein, a name that pays tribute to the science-fiction master Robert Heinlein.)
Proceeds from the contest will be distributed according to Uwingu's formula, which puts money into a fund to be given out as grants for research and education. Uwingu is structured as a profit-making venture, so Stern and his partners will get some of the money, too. Stern realizes that having people pay to suggest planetary names that have no official standing may be controversial, and he's willing to take the heat.
"Just spell our name right," he said.
His supporters include one of the world's foremost planet-hunters, Berkeley astronomer Geoff Marcy, who is one of Uwingu's advisers. In an email,?Marcy told NBC News he thought the idea of naming Alpha Centauri Bb sounded "marvelous."
"It should be fun and creative," Marcy said. "It hurts no one, and generates funding for research. What a perfect antidote to the modern crunch on funding in pure research!"
Uwingu's critics include Caltech astronomer Wladimir Lyra, who came up with his own proposal for naming extrasolar planets a few years ago. He's not crazy about the pay-for-play naming system. "What I would advocate is a classical way of naming the planets from our own myths, the way we name features on planets in our own solar system," Lyra told NBC News. "We can draw upon the expertise that the IAU has for naming things."
As long as people understand what they're buying ??and what's not for sale ??Uwingu's contest looks like an interesting and harmless experiment. Heck, it might even push the world's astronomers to reach consensus on names for the most prominent exoplanets. But what do you think? Feel free to weigh in with your comments below.
