CAPE CANAVERAL, Fla. (July 15, 2013)--NASA Monday announced the discovery of Neptune's 14th moon.
The moon turned up as a white dot in photos of Neptune from the Hubble Space Telescope.
The new moon, Neptune's tiniest at just 12 miles across, was designated S/2004 N 1.
The SETI Institute's Mark Showalter of Mountain View, Calif., made the discovery.
He was studying the segments of rings around Neptune when the white dot popped out, 65,400 miles from Neptune.
He tracked its movement in more than 150 pictures taken from 2004 to 2009.
The considerably bigger gas giant Jupiter has four times as many moons, 67.
