Larissa

Larissa was a daughter of Pelasgus. Harold Reitsema is now usually credited with the discovery of Larissa by ground-based stellar occultation observations. The first (and so far only) images of it were obtained by Voyager 2.

Larissa is irregular (non-spherical) in shape and appears to be heavily cratered, with no sign of any geological modification. Little else is known about it.

Larissa Neptune VII - 1989N2, 1981N1 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 is a city and the capital of the Thessaly Peripheries of Greece of Greece, and capital of the Larissa Prefecture.

LARISSA Larissa is a tiny moon of Neptune. 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.

Larissa Proteus Triton Nereid 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.

Number of satellites: 8 (Naiad, Thalassa, Despina, Galatea, Larissa, Proteus, Triton, and Nereid) The planet Neptune was the first planet to be predicted before it was discovered.

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.
