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 ...
Gliese 667 Cc, discovered in 2011 but announced in 2012, [145] is a super-Earth orbiting in the circumstellar habitable zone of Gliese 667 C. It is one of the most Earth-like planets known. Gliese 163 c, discovered in September 2012 in orbit around the red dwarf Gliese 163 [146] is located 49 light years from Earth.

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.
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.
