Vulcan Tops Online Voting to Name Pluto's Moons', PC Magazine
"Vulcan was the only candidate in the contest run by the SETI Institute to top 100,000 votes, garnering 174,062 votes out of about half a million cast in online voting that ended Monday at 6 a.m. Eastern. "Cerberus" was the other winning name with 99,432 votes, according to the Los Angeles Times."
"And with Starfleet's favorite son leading the charge, Vulcan quickly won the vote. "174,062 votes [out of nearly 450,000 cast] and Vulcan came out on top of the voting for the naming of Pluto's moons. Thank you to all who voted!" Shatner tweeted. Leonard Nimoy, who as Spock is probably Vulcan's best known ambassador, told the Associated Press, "If my people were emotional they would say they are pleased."
