It is a planet only about 3 times the mass of Earth orbiting in the habitable zone of the star Gliese 581. It is widely considered the most likely extrasolar planet to harbor life.
Gliese 581 g was discovered on September 29, 2010.
No. g liese 581c is a planet that orbits a star, Gliese 581.
3-6. The 3 planet model would have gliese 581 b too hot, gliese 581 c in the habitable zone, and gliese 581 d too cold. The 6 planet model would have gliese 581 e, b, and c too hot, gliese 581 g and d in the habitable zone, and gliese 581 f too cold.
Gliese 581 g is located approximately 20 light years away from Earth in the constellation Libra.
Goldilocks Zone or Goldilocks Planet.

The estimated temperature of Gliese 581 g is around -37 degrees Celsius (-35 degrees Fahrenheit). This temperature is an estimate based on the distance of the planet from its host star and its atmosphere composition.
Gliese 581 g is an exoplanet orbiting the star Gliese 581, located approximately 20.5 light years away in the constellation of Libra. It was believed to be in the habitable zone of its star where liquid water could exist on its surface, making it a potential candidate for hosting life. However, its existence has been debated and further observations are needed to confirm its properties.
The existence of Gliese 581 g, an exoplanet in the Gliese 581 system, is still a subject of debate among astronomers. Some studies have suggested its presence, while others have cast doubt on its existence due to methodological challenges associated with detecting such distant celestial bodies. Further research is needed to confirm the existence of Gliese 581 g definitively.
No. At 20.5 light years from Earth, and it only having been discovered, AND Terrans not having developed extra-light speed craft or wormhole technology, it would not be possible for anyone to have arrived at Gliese 581 G yet.
Gliese is not a planet but rather a star called Gliese 581. Stars like Gliese 581 do have atmospheres consisting of gases like hydrogen and helium. If you're referring to potential exoplanets orbiting Gliese 581, they may have atmospheres depending on their size, distance from the star, and other factors.
Gliese 581 c is too hot for life because it is closer to its star. This planet is similar to venus. This planet traps too much heat that causes a strong greenhouse effect. The temperature is too high and the atmosphere is nearly all carbon dioxide. Gliese 581 d is at the right distance for liquid water to exist. It is at the Goldilocks zone just like the earth. That means life could exist on Gliese d. This planet have the right temperature. It has a magnetic field and a rich oxygen and nitrogen atmosphere.
