Hubble finds undetected moon of Neptune

Neptune + moonsUsing Hubble Space Telescope images of Neptune taken between 2004 and 2009, astronomers discover a 14th moon circling the outermost planet of the solar system. Not given an official, mythologically-derived name yet, the moon is initially designated S/2004 N1, and is a small, dark body with a diameter of roughly 12 miles, making it Neptune’s smallest discovered satellite to date, orbiting the planet once a day at a distance of 65,400 miles.
