Rare six-planet system

[Graeme1858]

A rare star system with six exoplanets has been unlocked with the help of ESA’s Cheops mission. The discovery is particularly valuable because the planets’ orbital configuration shows that the system is largely unchanged since its formation more than a billion years ago.

Thanks for the article Graeme. The orbital periods are mind bendingly short!

From CNN:
"CNN — Astronomers have used two different exoplanet-detecting satellites to solve a cosmic mystery and reveal a rare family of six planets located about 100 light-years from Earth. The discovery could help scientists unlock the secrets of planet formation."

I don't know how old this discovery is because all CNN articles seem to never state when they were posted originally - only that they were updated recently.
