Naiad is in a 73:69 [[orbital resonance]] with the next outward moon, [[Thalassa (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&nbsp;km apart when they pass each other. Although their orbital radii differ by only 1850&nbsp;km, Naiad swings ~2800&nbsp;km above or below Thalassa's orbital plane at closest approach. Thus this resonance, like many such orbital correlations, serves to stabilize the orbits by maximizing separation at conjunction. However, the role of orbital inclination in maintaining this avoidance in a case where eccentricities are minimal is unusual.<ref name="JPLnews2019" /><ref name="Brozovic2019" />
