[9], Nereid is third-largest of Neptune's satellites, and has an average radius of about 178.5 kilometres (110.9 mi).

Nereid. [6][6] The thermal model also indicates that the surface roughness of Nereid is very high, likely similar to the Saturnian moon Hyperion. A new mission competing for selection under NASA's Discovery Program would try to untangle the mysteries of Neptune's strange moon Triton. Nereid Universe Today. Distant Moons of Neptune. Nereid's odd orbit suggests it might be a captured asteroid. [18] Voyager 2 obtained 83 images with observation accuracies of 70 km (43 mi) to 800 km (500 mi). Since 1987 some photometric observations of Nereid have detected large (by ~1 of magnitude) variations of its brightness, which can happen over years and months, but sometimes even over a few days. Kuiper Kuiper, 1949.

[13] Although the images obtained by Voyager 2 do not have a high enough resolution to allow surface features to be distinguished, Voyager 2 was able to measure the size of Nereid and found that it was grey in colour and had a higher albedo than Neptune's other small satellites.[2]. It is named after the Nereids, sea-nymphs of Greek mythology and attendants of the god Neptune. Regular moons are typically larger satellites with prograde, nearly circular orbits Nereid, which exhibits one of the largest satellite eccentricities, is believed to. Kepler Observes Neptune and Its Moons Triton and Nereid. To date there is no credible explanation of the variations, but, if they exist, they are likely related to the rotation of Nereid. Nereid moon &oldid 867927769 Commons gallery. The unusual orbit suggests that it may be either a captured asteroid or Kuiper belt object, or that it was an inner moon in the past and was perturbed during the capture of Neptune's largest moon Triton. On the other hand, not all astronomers who have observed Nereid have noticed such variations. Long-term observations of Neptune have allowed scientists observe storm formation and also to track storm evolution on the ice giant. NVNM 668 Nereid.

NVNM 636 Triton. [15], In 1991, a rotation period of Nereid of about 13.6 hours was determined by an analysis of its light curve. They persist even after a correction for distance and phase effects. This mythological link with Nereus is an appropriate one, because available evidence suggests that Halimede was originally a part of the larger moon Nereid. Nereid was discovered in 1949 by astronomer Gerard Kuiper. Nereid, another Neptune moon, is trapped in a dramatic boomerang orbit.

Nereid was discovered on 1 May 1949 by Gerard P. Kuiper on photographic plates taken with the 82-inch telescope at the McDonald Observatory. To date there is no credible explanation of the variations, but, if they exist, they are likely related to the rotation of Nereid. [6][6] The thermal model also indicates that the surface roughness of Nereid is very high, likely similar to the Saturnian moon Hyperion.

Neptune has two large moons that are easily seen from Earth, Triton and Nereid.

[18] Prior to Voyager 2's arrival, observations of Nereid had been limited to ground-based observations that could only establish its intrinsic brightness and orbital elements.
