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.
These include Gliese 581 d & g, [56] [57] [58] Gliese 667 Ce & f, [16] [59] Gliese 682 b & c, [9] Kapteyn b, [60] [61] and Gliese 832 c. [ 62 ] HD 85512 b was initially estimated to be potentially habitable, [ 63 ] [ 64 ] but updated models for the boundaries of the habitable zone placed the planet interior to the HZ, [ 65 ] [ 66 ] and it is ...
Artist's impression of Gliese 667 Cc. The brightest star in the sky is the red dwarf Gliese 667 C, which is part of a triple star system. [27] Gliese 667 Cc was originally described as one of two 'super-Earth' planets around Gliese 667 C, a dim red star that is part of a triple star system. The stars of this system have a concentration of heavy ...
This designation doesn't appear in the SIMBAD database, and more modern naming conventions use a separated lettering system where lower-case letters to refer to planets and upper-case letters to designate stars (e.g. Gliese 667 Cc is the 'c' planet orbiting Gliese 667C, which is the 'C' star of a triple system), making PSR B1620-26 b the ...
Gliese 667 C has three of them are in the habitable zone [73] including Gliese 667 Cc is estimated to have surface temperatures similar to Earth and a strong chance of liquid water. [74] Kepler-22b one of the first 54 candidates found by the Kepler telescope and reported is 2.4 times the size of the Earth, with an estimated temperature of 22 ...
