A tiny new moon has been spotted circling Neptune — the 14th known to be orbiting the faraway planet, the U.S. space agency said Monday.

The moon is the smallest ever glimpsed around Neptune and measures nearly 20 km across, based on observations from the Hubble Space Telescope, NASA said.

Neptune is the farthest planet from the sun, and NASA said the moon, named S/2004 N1, is about 100 million times fainter than the dimmest star that can be seen with the naked eye.
