    CAPE CANAVERAL, Fla. (AP) — Astronomers have discovered a rare in-sync solar system with six planets moving like a grand cosmic orchestra, untouched by outside forces since their birth billions of years ago.

    A pair of planet-hunting satellites — NASA’s Tess and the European Space Agency’s Cheops — teamed up for the observations.

    “Here we have a golden target” for comparison, said Adrien Leleu of the University of Geneva, who was part of an international team that published the results in the journal Nature.

    As gas planets, they’re believed to have solid cores made of rock, metal or ice, enveloped by thick layers of hydrogen, according to the scientists.

    In technical terms, it’s known as resonance that’s “precise, very orderly,” said co-author Enric Palle of the Institute of Astrophysics of the Canary Islands.

    The University of Bern’s Hugh Osborn, who was part of the team, was “shocked and delighted” when the orbital periods of this star system’s planets came close to what scientists predicted.
