The habitable zone of Gliese 581 compared with our Solar System's habitable zone, showing Gliese 581d near the outer edge. As the planet is not known to transit from Earth and atmospheric conditions are not observable with current technology, no atmosphere for the planet has been confirmed to date.
Gliese 581g, unofficially known as Zarmina's World, [28] was a candidate exoplanet claimed to orbit Gliese 581, but its existence was ultimately refuted. [45] It was thought to orbit with a period of 36.6 days at a distance of 0.146 AU, placing it within the habitable zone, and to have a minimum mass of 3.1 M 🜨 .
The team released a paper of their findings dated 27 April 2007, published in the July 2007 journal Astronomy & Astrophysics. [1] At the time of discovery, it was reported to be the first potentially Earth-like planet in the habitable zone of its star [5] [6] and the smallest-known exoplanet around a main-sequence star, but on 21 April 2009, another planet orbiting Gliese 581, Gliese 581e ...
The habitable zone of Gliese 581 compared with the Solar System's habitable zone. The 2007 discovery of Gliese 581c, the first super-Earth in the circumstellar habitable zone, created significant interest in the system by the scientific community, although the planet was later found to have extreme surface conditions that may resemble Venus.

Gliese 581: Libra: 15 h 19 m 26.83 s: −07° 43′ 20.2″ ... Planet b orbits in the habitable zone, but it and planet c are massive enough to be brown dwarfs. HD ...
Scientists have found a new Earth-like planet that could support alien life – just 40 light-years away.. The planet is a remarkable discovery in the search for habitable worlds: it is slightly ...
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.
A potentially habitable exoplanet that is roughly similar in size to Earth has been found in a system located 40 light-years away, according to a new study. ... Dubbed Gliese 12 b, the planet ...
