Neptune's 14th Moon discovered by NASA

The U.S. space agency in July 2013 announced the discovery of Neptune’s 14th moon. The Hubble Space Telescope captured the moon as a white dot in photos of the planet on the periphery of our solar system.


The new moon, Neptune’s tiniest at just 19.3 km across, and is designated as S/2004 N 1.

The Neptune 14th moon was actually discovered by the SETI Institute’s Mark Showalter while studying the segments of rings around Neptune when he spotted the white dot popping out, 105250 km from Neptune. He tracked its movement in more than 150 pictures taken from 2004 to 2009.
