Nereid/Orbital period
Where is Nereid moon?
Neptune
Overview. Nereid is one of the outermost of Neptune’s known moons and is among the largest. Nereid is unique because it has one of the most eccentric orbits of any moon in our solar system. Nereid is so far from Neptune that it requires 360 Earth days to make one orbit.
How far is Nereid from Neptune?
5,513,400 km
Its mean distance from Neptune is 5,513,400 km (3,425,900 miles), which is about 15 times farther from Neptune than the next closest known moon, Triton. Nereid is exceedingly faint, making observations with even the largest Earth-based telescopes very difficult.
What is the surface of Nereid like?
Nereid has a geometric albedo of 0.14, more consistent with an ice–silicate surface; ice has been detected on its surface. Its unusual orbit means that the satellite is probably not in synchronous rotation.
How was Nereid discovered?
Nereid was discovered on May 1, 1949 by Gerard P. Kuiper with a ground-based telescope. It was the last satellite of Neptune to be discovered before Voyager 2’s discoveries four decades later.
Does Neptune have a moon named Nereid?
Neptune’s second moon to be discovered is called Nereid. It was found in 1949 by Gerard Kuiper, an American astronomer who was born in the Netherlands. In Greek mythology, the Nereids are sea nymphs, and are helpful to sailors that are fighting dangerous storms. Nereid is the outermost of Neptune’s moons.

Who discovered the moon Nereid on Neptune?
Nereid was discovered on 1 May 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. It is named after the Nereids , sea-nymphs of Greek mythology and attendants of the god Neptune.
