NASA detects Neptune's strange two-month orbital movement

Astronomers from NASA's Jet Propulsion Laboratory in Pasadena, California discovered two of the fourteen moons of Neptune orbiting the planet while dancing.

According to research, the most hidden moons, Najad and Talasa, orbit Neptune in a strange unison. Najad, with its tilted orbit, takes seven hours to complete a revolution, while Talas needs its outer orbit seven and a half hours to take Neptune.

If one looks at Nayad from Thalassa, he will notice that the most determined moon follows a zigzag pattern as it passes by. Because of its rounded orbit, Nayad will be seen twice above and twice below as he overtakes the slower Thalassa by four laps.

While both orbits are only 1,850 kilometers apart, they never get very close to each other because they are 3,540 kilometers apart even when they cross each other. Reason – both partners locked in 'dance of avoidance"What keeps their orbits stable" by never approaching.

Leading author of the study 'Orbits and resonances of Neptune's regular moons"Explain Marina Bozovic," We refer to this recurrent pattern as resonance. There are many different types of "dances" that can follow planets, moons and asteroids, but this has never been seen. "

Researchers believe the previous satellite system was disrupted by Triton, Neptune's largest moon. The most decisive moons were thrown into their orbits and eventually established resonances.

Researchers have also used inferences from the Hubble Space Telescope to find out about the properties of Neptune's moon. For the first time, they were able to calculate the mass and density found similar to ice water.
