Larissa [LA-ree-suh] is only about 48,800 kilometers (30,300 miles) from Neptune's clouds, and circles the planet in 13 hours, 18 minutes. Its diameter is about 190 kilometers (120 miles).

LARISSA
Larissa is a tiny moon of . It was discovered using NASA's Voyager 2 mission in 1989. It orbits 73,550 km from the center of Neptune and is about 104 x 89 km.
Larissa was a daughter of Pelasgus.
Proteus
Proteus is Neptune's second largest moon, but it is still not very big. As you can see by looking at the picture, this world is not very round.

Viewing Guide
The fourth-largest planet in the solar system is so far away that you need a telescope to find it. Neptune stages its best appearance in August.
Larissa (NASA Thesaurus) A natural satellite of Neptune, orbiting at a mean distance of 73,600 kilometers. Larmor frequency (NASA SP-7, 1965) See cyclotron frequency.
The next one out, Larissa, was actually discovered in 1981, when it blocked a star. This was attributed to the ring arcs, but later was found to be the moon, being re-discovered by Voyager 2 in 1989.
Proteus and Larissa are irregular in shape and appear to have heavily cratered surfaces.

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.
The names Galatea and Larissa were controversial since asteroids previously had been given those names. Names are assigned by the nomenclature committee of the International Astronomical Union (IAU).

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.

No further moons were found until Voyager 2 flew by Neptune in 1989. Voyager 2 recovered Larissa and discovered five new inner moons, bringing the total of known moons of Neptune to eight.
The next farthest out, Larissa was originally discovered in 1981 when it had occulted a star. This had been attributed to ring arcs, but when Voyager 2 observed Neptune in 1989, it was found to have been caused by the moon.
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.
