Cheops confirmed the existence of four warm exoplanets with sizes between Earth and Neptune

Caption

Cheops confirmed the existence of four warm exoplanets with sizes between Earth and Neptune, orbiting their stars closer than Mercury our Sun. These so-called mini- Neptunes are unlike any planet in our Solar System and provide a 'missing link' that is not yet understood. Mini-Neptunes are among the most common types of planets known, and astronomers are starting to find more and more orbiting bright stars.
