Discovery of a new moon orbiting Pluto has been named 'Vulcan' by a contest at the Carl Sagan Center for the Study of Life, by Star Trek fans.
Leanord Nimoy said, "It's a logical choice."
Pluto, named after the Roman God of the Underworld, was discovered in 1930 by Clyde Tombaugh. The Moon now named Vulcan was discovered in 2001, named P4 until now. Five moons have been discovered orbiting Pluto.
