Default NASA Finds Neptune Moons Locked in ‘Dance of Avoidance’

NASA Finds Neptune Moons Locked in ‘Dance of Avoidance’
Quote:
Even by the wild standards of the outer solar system, the strange orbits that carry Neptune's two innermost moons are unprecedented, according to newly published research.

Orbital dynamics experts are calling it a "dance of avoidance" performed by the tiny moons Naiad and Thalassa. The two are true partners, orbiting only about 1,150 miles (1,850 kilometers) apart. But they never get that close to each other; Naiad's orbit is tilted and perfectly timed. Every time it passes the slower-moving Thalassa, the two are about 2,200 miles (3,540 kilometers) apart.

Thumbs up interesting

The two little moons are locked in a 'resonance' where they eternally avoid collision with each other in Neptune's gravitational field ...sounds almost supernatural. Cool stuff.

Thanks for posting that Nikola.

Resonance in three of Jupiter's moons;


I thought those interested in astrophysics might like this depiction.

Neptune's moons follow a sine vs. cosine wave orbital resonance which gets a little technical: however, the graphic is really neat to watch.

Thanks to Nikola for posting and to Tom who made me think of my astrophysics.
