(CNN) -- It's logical -- especially when it has the support of Capt. Kirk and Mr. Spock. Residents of Earth and other planets have until Monday to weigh in on new names for two of Pluto's moons, by voting on a website set up by the SETI Institute. Based on those votes, the Northern California scientific research organization will then propose names to the International Astronomical Union, which makes the final call. And the runaway top pick, as of Friday evening, is Vulcan. Roman mythology aficionados may see that as a tribute to the god of fire. But for others -- most notably, for legions of Star Trek fans -- it is better known as the home planet of Spock, the ever rational, ever loyal member of the starship Enterprise.

William Shatner and Leonard Nimoy have urged Trekkies to vote for the Vulcan name
Leonard Nimoy
None other than @placeholder, who played Spock in the long-running Star Trek television series and string of movies, endorsed as "logical" the idea of naming one of the moons Vulcan.

@placeholder -- or more accurately his human facsimile, William Shatner -- started his effort by urging Trekkies to write the SETI Institute to get Vulcan added as an option.

Since being added as one of 21 alternatives -- and with the help of regular online proddings by @placeholder, urging fans to vote Vulcan -- Spock's home has rocketed up the official online vote tally.

But the second-place finisher has a nice consolation prize, since the @placeholder will be proposing two names.

That would give it a timelessness beyond the two hours or so of any such @placeholder film, allowing the beloved sci-fi franchise's fans to rest easy knowing that Vulcan itself might "live long and prosper" for centuries, if not eons to come.
