According to an announcement from the National Center for Scientific Research (CNRS) Gliese 581d third planet orbiting the red dwarf, “could be the first potentially habitable planet” discovered to date.
This statement specifies that to be seven times more massive than Earth, apparently rocky, with a climate conducive to the presence of liquid water and life, this planet could be tentatively habitable for the human race.
Detected in 2007 to 20 light years of the solar system, Gliese 581d was judged as too cold then to be considered “habitable”, which means with compatible temperatures with the presence of liquid water on its surface.
According accurately the CNRS, the exoplanet that orbits a star slightly warm receives three times less energy than the Earth receives from the Sun likewise. Gliese 581d, could benefit from a greenhouse climate to offer a “warm climate to the point of allowing the formation of oceans, clouds, and rain.”
