Earthlike Planet, Gliese 581 (Gliza) habitable zone? Gliese 581 g. Gliese 581 g has attracted attention because it is near the middle of the habitable zone of its parent star.
That means it could sustain liquid water on its surface and could potentially host life similar to that on Earth (the planet is expected to have temperatures around −37 to −12 °C). If it is a rocky planet, favorable atmospheric conditions could permit the presence of liquid water, a necessity for all known life, on its surface. With a mass 3.1 to 4.3 times Earth's, Gliese 581 g is considered a super-Earth and is the planet closest in size to Earth known in a habitable zone.
This makes it the most Earth-like Goldilocks planet found outside the Solar System and the exoplanet with the greatest recognized potential for harboring life.[8] And NSF-Funded Research Finds First Potentially Habitable Exoplanet. NASA and NSF-Funded Research Finds First Potentially Habitable Exoplanet A team of planet hunters from the University of California (UC) Santa Cruz, and the Carnegie Institution of Washington has announced the discovery of a planet with three times the mass of Earth orbiting a nearby star at a distance that places it squarely in the middle of the star's "habitable zone.
" This discovery was the result of more than a decade of observations using the W.
