Neptune is the eighth or, occasionally, the ninth planet from the Sun due to Pluto's eccentric orbit, and the outermost gas giant in our solar system.
NAIAD
Naiad is a tiny moon of . It was discovered using NASA's Voyager 2 mission in 1989. It orbits 48,230 km from the center of Neptune and is about 58 km in diameter.
Naiad is the closest moon to the surface of Neptune. Naiad is too small to be shaped like a ball. Instead it is irregularly shaped, more like an asteroid. This world was discovered in 1989 by Voyager 2.

Voyager 2 discovered six new ones, which are named Naiad, Galatea, Thalassa, Larissa, Proteus, and Despina. Since then, five more were discovered but have yet to be named. Either way, this gives us a grand total of 13 satellites.
Neptune has eight known moons: Triton, Thalassa, Naiad, Despina, Galatea, Larissa, Proteus and Nereid.
Voyager 2 spacecraft visited Neptune on August 25, 1989.
Neptune was named after the Roman god of the sea.
The first four moons of Neptune, Naiad, Thalassa, Despina, and Galatea, are so close to Neptune that they orbit within its ring system. Little is known about them.
Neptune's innermost four moons, Naiad, Thalassa, Despina, and Galatea, orbit close enough to be within Neptune's rings. The next farthest out, Larissa was originally discovered in 1981 when it had occulted a star.
So far, eight moons have been discovered orbiting Neptune. They are (from nearest the planet to furthest): Naiad, Thalassa, Despina, Galatea, Larissa, Proteus, Triton and Nereid.
