Proteus (pictured at left) the 2nd largest of Neptune's moons was discovered by Voyager in 1989.. Triton is next in orbital distance.

Among all moons in the solar system, it has the most eccentric orbit.

Keen-eyed observers can also spot Neptune’s tiny moon Nereid at day 24.

Halimede is next and takes just over 5 years to orbit.

It was the second discovered moon of Neptune. 1 Unusual orbits. ... Nereid is the third-largest moon of Neptune. We know next to nothing about Nereid. Nereid is about 340 kilometers (210 miles) in diameter and is so far from Neptune that it requires 360 days to make one orbit.

At a distance of 354,759 km from Neptune, it also sits between the planet’s inner and outer moons.

They take 25 years to orbit Neptune at an average of 125 times the distance between Earth and the Moon. It has a … Voyager's best photos of Nereid were taken from … Nereid is the third-largest moon of Neptune. Neptune is the eighth and most distant planet from the Sun in our solar system. One hundred years later the second moon, Nereid was found.
View of Nereid obtained by Voyager 2 on Aug. 24, 1989 at a distance … The planet neptune is about 2795084800 miles or 4498252900 kilometers away from the sun.

Nereid’s orbit is the most highly eccentric of any planet or satellite in the solar system; its distance from Neptune varies from 1,353,600 to 9,623,700 kilometers. Most of Neptune's moons are named after sea nymphs . Nereid is about 340 kilometers (210 miles) in diameter and is so far from Neptune that it requires 360 days to make one orbit. Nereid comes next and is the 3rd largest moon taking almost an Earth year to orbit Neptune once. Nereid Neptune II Nereid [NEER-ee-ed] was discovered in 1949 by astronomer Gerard Kuiper. Rowe

Neptune has over 13 know moons like Triton and nereid. The planet Neptune appears on day 15, followed by its moon Triton, which looks small and faint. The largest moon is Triton which was discovered by William Lassell just seventeen days after Neptune was found. The Hubble Telescope found the 14th moon in 2013. It is named after the Nereids, sea-nymphs of Greek mythology and attendants of the god Neptune. Neptune is not moving backward but appears to do so because of the changing position of the Kepler spacecraft as it orbits around the sun. Neptune has a total of 14 known moons. It is a gas giant. Nereid [NEER-ee-ed] was discovered in 1949 by astronomer Gerard Kuiper. Nereid was discovered on May 1, 1949, by Gerard P. Kuiper, on photographic plates taken with the 82-inch telescope at the McDonald Observatory.He proposed the name in the report of his discovery. One of them is Nereid, Neptune’s third largest moon located behind Triton and Proteus. Nereid’s odd orbit indicates that it may be a captured asteroid or Kuiper Belt object. Discovery and naming. Today, on this day May 1, 1949, Neptune’s moon Nereid was discovered. Open Issues. Voyager's best photos of Nereid were taken from about 4.7 million kilometers (2.9 million miles).
