Hubble Discovers New Neptune Moon
Astronomers using the Hubble Space Telescope have found another moon circling Neptune, a giant planet located about 30 times farther away from the sun than Earth. The new moon was too small to be noticed by Voyager 2′s cameras when it completed its flyby of the planet in 1989.
The newly found moon, temporarily designated S/2004 N 1, brings Neptune’s orbital brood to 14. With an estimated diameter of no more than 12 miles, the new moon is Neptune’s smallest.
S/2004 N 1 is located about 65,400 miles from the planet, between the orbits of sister moons Larissa and Proteus, and it circles Neptune about every 23 hours.
