Galatea 

Galatea closely orbits Neptune once in 10 hours, 18 minutes and is very similar to Despina in its irregularity of shape and its lack of geological activity. Galatea orbits the same direction of Neptune and is close to its equatorial plane. The satellite is at a distance of 37,200 kilometers (23,100 miles) from Neptune's surface and was discovered in 1989 hrough analyzing photographs taken by Voyager 2.
