CTOnews.com, December 1 (Xinhua)-- an international team of senior astronomers, using NASA's Transit Exoplanet Reconnaissance Satellite (TESS) and ESA's Exoplanet Reconnaissance Satellite (CHEOPS), have discovered a "perfect solar system" with six planets in synchronous operation.

The "perfect solar system" is located in the galactic constellation Coma Berenices, 100 light-years from Earth, and is one of the few synchronous solar systems found so far.

This rare discovery of the solar system excites astronomers and can help astronomers learn more about the formation and evolution of planets. The video attached to CTOnews.com is as follows:

The perfect Solar system, whose star is HD 110067, has found a total of six planets, about two to three times the size of Earth, but closer to the gaseous giants in the solar system, with orbital periods ranging from 9 to 54 days.

The six planets are numbered with the letters b, c, d, e, f and g from near to far away from the star.

Researchers found that HD110067's three inner planets are dancing in precise 3:2-3:2 resonance chains: when the innermost planet orbits the star nine times, the second planet rotates six times and the third planet rotates four times.

For every six orbits of the nearest planet b to the star HD110067, the outermost planet g completes one orbit; when planet c orbits the star three times, planet d orbits the star twice; when planet e orbits the star four times, planet f orbits the star three times.

This harmonious rhythm creates a resonant chain, with all six planets aligned every few orbits. The two outermost planets have orbital periods of 41 days and 54.7 days, respectively. Every time the outermost planet completes its orbit, the innermost planet completes its six-cycle orbit.

The study's co-author, Enrique Paler of the Canary Islands Institute of Astrophysics (Institute of Astrophysics of the Canary Islands), said that in technical terms, this is a "precise, very orderly" resonance.

Although astronomers have observed 40 to 50 synchronous solar systems, none of them works so perfectly with so many planets, Paller said.

Hugh Osborn of University of Bern University is part of the team. He said he was "shocked and delighted" to find that the planetary orbital period of the star system was close to what scientists had predicted.
