The paper also announced the discovery of planet 'f,' a 7-Earth mass planet with a 433-day orbit around Gliese 581. Planet 'g' was calculated to have an orbital period of only 37 days. Although an ...

The two finds increased the number of known planets in the Gliese 581 system to six (four others ... the very weak signals of planets f and g," Vogt said. While Vogt's team published its discovery ...

The planetary system around the red dwarf Gliese 581, one of the closest stars to the Sun in the galaxy, has been the subject of several studies aiming to detect the first potentially habitable ...

Twenty light-years away, orbiting the star Gliese 581, was a rocky planet thought to be three to four times the mass of the Earth, smack in the middle of the so-called “Goldilocks zone ...

The planet Gliese 581d is at the colder outer edge of the "Goldilocks zone" in which liquid water can be sustained. Now a study in Astrophysical Journal Letters, external suggests its atmosphere ...

Last time we wrote about the possibly-habitable exoplanets orbiting red dwarf star Gliese 581 was back when we were possibly lie in the habitable zone. 581c lies in a questionably-habitable spot ...
