Neptune Moon Dance (animation)


The Voyager 2 spacecraft
discovered Neptune moons Naiad and Thalassa in 1989. The moonlets are only about
60 miles (100 km) wide. If we race along with
Thalassa around Neptune, Naiad appears to be moving
in a wave -like pattern. That’s because,
compared to Thalassa, Naiad’s orbit is tilted
by about five degrees. It takes about seven hours
to complete the orbits. Naiad spends half of each
orbit above Thalassa and the other half below. If we plot multiple orbits, we see Naiad in a constant
dance with Thalassa. This is called a resonance.
