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 largest star in the system, Gliese 667 A (GJ 667 A), is a K-type main-sequence star of stellar classification K3V. [2] It has about 73% [5] of the mass of the Sun and 76% [2] of the Sun's radius, but is radiating only around 12-13% of the luminosity of the Sun. [15] The concentration of elements other than hydrogen and helium, what astronomers term the star's metallicity, is much lower ...
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.
Gliese 12 b, which orbits a cool, red dwarf star located just 40 light-years away, promises to tell astronomers more about how planets close to their stars retain or lose their atmospheres. In ...
