Neptune’s 14th Moon Discovered

The U.S. space agency has 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 outskirts of our solar system.

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

The SETI Institute’s Mark Showalter made the discovery. He was studying the segments of rings around Neptune when the white dot popped out, 105,250 km from Neptune. He tracked its movement in more than 150 pictures taken from 2004 to 2009.
