Gliese 581b or Gl 581b is an exoplanet orbiting within the Gliese 581 system, located 20.5 light-years (6.3 parsecs) away from Earth in the Libra constellation. It is the first planet discovered of three confirmed in the system so far, and the second in order from the star.
Gliese 581 (/ ˈ ɡ l iː z ə /) is a red dwarf star of spectral type M3V which hosts a planetary system, 20.5 light-years (6.3 parsecs) away from Earth in the constellation Libra. Its estimated mass is about a third of that of the Sun, and it is the 101st closest known star system to the Sun. [15] Gliese 581 is one of the oldest, least active ...
Gliese 581d / ˈ ɡ l iː z ə / (often shortened to Gl 581d or GJ 581d) is a doubtful, and frequently disputed, exoplanet candidate orbiting within the Gliese 581 system, approximately 20.4 light-years away in the Libra constellation. It was the third planet claimed in the system and the fourth (in a 4-planet model) or fifth (in a disproven 5 ...
Libra is home to the Gliese 581 planetary system, which consists of the star Gliese 581 and three confirmed planets. This system gained attention in the late 2000s and early 2010s as the subject of some of the earliest claims of potentially habitable exoplanets, [ 10 ] [ 11 ] but it is now known that Gliese 581c is too hot to be potentially ...
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 ...

The newly discovered planet is called Gliese 12b and researchers say that even if we cannot find whether it is home to alien life then it will help in our search for other worlds that might be.
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 ...
