GJ 667Cc is a super-Earth exoplanet confirmed in 2012, orbiting within the habitable zone of a red dwarf star in the triple-star system GJ 667. Located approximately 22 light-years from Earth, it has a mass at least 3.8 times that of Earth and completes an orbit every 28 days. Its discovery, made using radial velocity measurements, added to the growing list of potentially habitable planets found a...

Proxima Centauri b

Proxima Centauri b is an exoplanet orbiting Proxima Centauri, the closest star to our Sun. This super-Earth resides within its star’s habitable zone, raising possibilities for liquid water on its surface. Its proximity makes it a key target for astronomical study and future investigation by scientists examining potentially habitable worlds beyond our solar system.
