ESA’s Cheops helps unlock rare six-planet system

ESA’s Cheops helps unlock rare six-planet system

by Daniela Sicilia | Nov 30, 2023 | Cheops, Exoplanets and Astrobiology, paper, Projects, RSN2

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.

Its name is Toi-1853b and it is extremely peculiar: every 30 hours it completes one complete revolution around its star (the Earth takes a year to complete one complete revolution around the Sun), it has a radius comparable to Neptune’s (3.5 Earth radii, hence...

Data from ESA’s exoplanet mission Cheops has led to the surprising revelation that an ultra-hot exoplanet that orbits its host star in less than a day is covered by reflective clouds of metal, making it the shiniest exoplanet ever found.

ESA’s exoplanet mission Cheops confirmed the existence of four warm exoplanets orbiting four stars in our Milky Way. These exoplanets have sizes between Earth and Neptune and orbit their stars closer than Mercury our Sun. These so-called mini-Neptunes are unlike any...
