Gliese 667 Cb is an exoplanet orbiting the star Gliese 667 C, a member of the Gliese 667 triple-star system. It is the most massive planet discovered in the system and is likely a super-Earth or a mini-Neptune. Orbital-stability analysis indicates that it cannot be more than twice its minimum mass.
Illustration of the inferred size of the super-Earth CoRoT-7b (center) in comparison with Earth and Neptune. A Super-Earth or super-terran or super-tellurian is a type of exoplanet with a mass higher than Earth, but substantially below those of the Solar System's ice giants, Uranus and Neptune, which are 14.5 and 17.1 times Earth's, respectively.

Gliese 581c / ˈ ɡ l iː z ə / (Gl 581c or GJ 581c) is an exoplanet orbiting within the Gliese 581 system. It is the second planet discovered in the system and the third in order from the star. With a mass about 6.8 times that of the Earth, it is classified as a super-Earth (a category of planets with masses greater than Earth's up to ten ...
Lacaille 9352 c is considered a Super-Earth with a minimum mass of 7.6 Earth masses. [4] With an orbital period of 21.8 days, the exoplanet is located at 0.12 AU from the star, which is close to the inner edge of the habitable zone (but still outside). [5] The exoplanet has a calculated equilibrium temperature of 352 K (79 °C; 174 °F). [2]
Gliese 667 Cc (also known as GJ 667 Cc, HR 6426 Cc, or HD 156384 Cc) [2] is an exoplanet orbiting within the habitable zone of the red dwarf star Gliese 667 C, which is a member of the Gliese 667 triple star system, approximately 23.62 light-years (7.24 parsecs; 223.5 trillion kilometres) away in the constellation of Scorpius.
The distance separating the planet and its star is just 7% of the distance between Earth and the Sun, and the planet receives 1.6 times more energy from its star than Earth does from the Sun.
Gliese 581g / ˈ ɡ l iː z ə / was a candidate exoplanet postulated to orbit within the Gliese 581 system, twenty light-years from Earth. [9] It was discovered by the Lick–Carnegie Exoplanet Survey, and was the sixth planet claimed to orbit the star; [10] however, its existence could not be confirmed by the European Southern Observatory (ESO) / High Accuracy Radial Velocity Planet Searcher ...
Scientists using Nasa’s Webb telescope have found an icy “super-Earth” that could be home to alien life. When researchers first discovered the planet, known as LHS 1140 b, they thought it ...
