Potato-shaped Naiad is most likely made up of fragments of Neptune's original satellites, which were smashed up by disturbances when the ice giant captured its largest moon, Triton. Naiad is anything but ordinary! That is about one-sixtieth the size of the Earth’s Moon. Naiad, the closest regular moon, is also the second smallest among the inner moons … Halimede is one of three tiny moons ranging in size from 18 to 24 miles (30 to 40 kilometers) discovered. Naiad is a very small satellite with a diameter of only approximately 58 kilometers. Overview.
Halimede, Laomedeia and Sao were discovered through the use of Earth-based telescopes—his was the first time a Neptunian moon discovery had occurred by telescope since the discovery of Nereid in 1949 by Gerard Kuiper. Discovery. In many cases, the lives of crew and passengers depend on the strength and design integrity of our boats. 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. Overview. Naiad was the last moon to be discovered during the Voyager 2 flyby in September 1989.
