"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.

The find, announced Wednesday, can help explain how solar systems across the Milky Way galaxy came to be. This one is 100 light-years away in the constellation Coma Berenices. A light-year is 5.8 trillion miles.

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

This star, known as HD 110067, may have even more planets. The six found so far are roughly two to three times the size of Earth, but with densities closer to the gas giants in our own solar system. Their orbits range from nine to 54 days, putting them closer to their star than Venus is to the sun and making them exceedingly hot....

This solar system is unique because all six planets move similar to a perfectly synchronized symphony, scientists said. In technical terms, it’s known as resonance that’s “precise, very orderly,” said co-author Enric Palle of the Institute of Astrophysics...."

Just to Know!

A recent study published in Nature has unveiled the discovery of six exoplanets orbiting a nearby bright star, HD 110067, located in the Coma Berenices constellation.

These planets referred to as ‘sub-Neptunes’, were detected and characterized by using data from two space telescopes: National Aeronautics and Space Administration's (NASA) Transiting Exoplanet Survey Satellite (TESS) and European Space Agency’s(ESA) CHaracterising ExOPlanet Satellite (CHEOPS).

Planets with radii between that of the Earth and Neptune are referred to as ‘sub-Neptunes’.

Calculations of their masses and densities indicate the presence of relatively low-density atmospheres, potentially rich in hydrogen.

All six planets are in resonant orbits, in which the planets exert regular forces on each other as they orbit. This feature suggests that the system remains practically unchanged since its birth, at least four billion years ago.

6 planets dancing around their star discovered

A system composed of 6 planets has been discovered, whose orbits are so regular and in harmony as to suggest a dance similar to a waltz. Described in the magazine Nature, the planets are 100 light years from Earth, in the constellation Coma Berenices, and their star, HD 110067, is the brightest known so far to have a system of more than 4 exoplanets. The discovery is a mine of data on the…
