A moon of Neptune, Naiad ("NYE ad" [UK, US] or "NAY ad" [US]) is named after the Naiads of Greek legend.

Naiad was the last of the satellites discovered in 1989 by Voyager 2. It is irregularly shaped and shows no sign of any geological modification. Since its orbit is below Neptune's synchronous orbit radius it is slowly decaying due to tidal forces and will one day impact on Neptune's surface, or will break up into a planetary ring due to tidal forces (once inside its Roche limit).

  • Orbital radius: 48,227 km
  • Radius: 48 x 30 x 26 km
  • Mass: 1.9×1017 kg
  • Estimated density: 1.2 g/cm3
  • Orbital period: 0.294 d (7 h 6 min)
  • Orbital inclination: 4.746°
