Gliese 536 b also known as GJ 536 b [2] [1] [3] is a nearby [5] [6] Super-Earth sized exoplanet orbiting interior to the circumstellar habitable zone [5] [6] of the red dwarf (M1) [1] star Gliese 536 every 8.7 days. Due to its short orbital period it could help with future studies of biological activity on exoplanets.
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 667 Cc is a super-Earth, an exoplanet with a mass and radius greater than that of Earth, but smaller than that of the giant planets Uranus and Neptune. It is heavier than Earth with a minimum mass of about 3.7 Earth masses. [5] The equilibrium temperature of Gliese 667 Cc is estimated to be 277.4 K (4.3 °C; 39.6 °F). [6]
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]
The designation Gliese 486 comes from the Gliese Catalogue of Nearby Stars. This was the 486th star listed in the first edition of the catalogue. In August 2022, this planetary system was included among 20 systems to be named by the third NameExoWorlds project. [8] The approved names, proposed by a team from Spain, were announced in June 2023.
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 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.
