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.

2024年10月24日 · GJ 667 C c is a super Earth exoplanet that orbits a M-type star. Its mass is 3.8 Earths, it takes 28.1 days to complete one orbit of its star, and is 0.125 AU from its star. Its discovery was announced in 2013.

2012年2月17日 · The extra-solar planet GJ667Cc (or Gliese 667Cc) has been declared the most Earth-like object known outside of our solar system. It orbits a type of star which is studied at the Institute of Theoretical Astrophysics.

Gliese 667 (142 G. Scorpii) is a triple-star system in the constellation Scorpius lying at a distance of about 7.2 parsecs (23 light-years) from Earth. All three of the stars have masses smaller than the Sun. To the naked eye, the system appears to be a single faint star of magnitude 5.89.

A team of astronomers has combined new observations of Gliese 667C with existing data from HARPS at ESO’s 3.6-metre telescope in Chile, to reveal a system with at least six planets.

Gliese 667Cc is at the center of an epic controversy in astronomy—a fight over the validity of data, the nature of scientific discovery, and the ever-important question of who got there first.

2013年6月25日 · Researchers used new observations of Gliese 667C to find evidence of up to seven planets, including three super-Earths in the habitable zone.

2024年2月22日 · Gliese 667 Cc is an exoplanet located in the Gliese 667 star system, approximately 22 light-years away from Earth. While there is limited information available about the specific characteristics of Gliese 667 Cc's atmosphere, scientists have made some speculations based on its estimated size, distance from its host star, and other factors.

2022年7月29日 · The M1.5V star GJ 667C (Gliese 667C) is a faraway member of a triple star system. It orbits the central binary GJ 667AB (a K3V + K5V binary system) at a projection distance of ~230 AU. GJ 667C is known to host several super-Earth planets.
