Proteus, (Neptune VIII, S/1989 N 1) is the largest inner satellite and the second largest moon of Neptune. Proteus was discovered by Voyager 2 during its flyby of Neptune in 1989. It was later named Proteus, the shape-shifting sea-god of Greek mythology. Proteus is tidally locked to Neptune in that the same side faces Neptune throughout its orbit.
