Naiad is in a 73:69 orbital resonance with the next outward moon, Thalassa, in a "dance of avoidance". As it orbits Neptune, the more inclined Naiad successively passes Thalassa twice from above and then twice from below, in a cycle that repeats every ~21.5 Earth days. The two moons are about 3540 km apart when they pass each other.

2024年11月3日 · Naiad was the last moon to be discovered during the Voyager 2 flyby in September 1989. Potato-shaped Naiad is most likely made up of fragments of Neptune's original satellites, which were smashed up by disturbances when …

Naiad or Neptune III is the closest moon to Neptune named after the Naiads of Greek legend. It was found sometime before mid-September, 1989 from the images taken by the Voyager 2 probe. The last moon to be discovered during the flyby, it was designated S/1989 N 6.

2013年10月8日 · By analyzing photos taken by the Hubble Space Telescope, scientists at the SETI Institute in Mountain View, Calif., have caught sight of Naiad, the innermost of Neptune's moons. The 62-mile-wide...

2013年10月8日 · Voyager spacecraft discovered this moon in 1989, but since then it's been an elusive target. With new techniques to suppress Neptune's glare, Naiad is found again. Learn more on EarthSky.

Naiad is a moon of planet Neptune and is likely a rubble pile that has re-accreted from fragments of the original moons of Neptune that collided after the moon Triton was captured. Naiad is slowly spiraling down toward Neptune and will either smash …

Naiad, named after the naiads of Greek legend, is the innermost satellite of Neptune and the nearest to the center of any gas giant with moons with a distance of 48,224 km from the planet's center. Its orbital period is less than a Neptunian day, resulting in tidal dissipation that will cause its orbit to decay.

Naiad, also known as Neptune III, is the innermost satellite of Neptune, named after the Naiads of Greek legend. The moon has a orbital period less than a Neptunian day and will therefore cause tidal dissipation and orbit decay, eventually resulting in it being destroyed in Neptune's atmosphere or turned into a new ring.

Naiad, the last satellite discovered, is about 54 kilometers (33 miles) in diameter and orbits Neptune every 7 hours and 6 minutes about 23,200 kilometers (14,400 miles) above the clouds. It is irregularly shaped and shows no sign of any geological modification.

Naiad is Neptune's innermost and smallest moon, discovered by Voyager 2 in 1989. Its orbit is less than a Neptunian day, causing tidal dissipation that will eventually lead to its decay. Naiad is irregularly shaped and may have been formed by rubble from Neptune's original satellites. It is in an orbital resonance with the next outward moon ...
