Gliese 581d / ˈ ɡ l iː z ə / (often shortened to Gl 581d or GJ 581d) is a doubtful, and frequently disputed, exoplanet candidate orbiting within the Gliese 581 system, approximately 20.4 light-years away in the Libra constellation. It was the third planet claimed in the system and the fourth (in a 4-planet model) or fifth (in a disproven 5 ...
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 🜨 .
Gliese 581c, [46] Gliese 581g, [47] [48] Gliese 581b, [49] and Gliese 581e [50] may be tidally locked to their parent star Gliese 581. Gliese 581d is almost certainly captured either into the 2:1 or the 3:2 spin–orbit resonance with the same star. [51] All planets in the TRAPPIST-1 system are likely to be tidally locked. [52] [53]
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.
Gliese 581d: Gliese 581: 2007 Orbits a red dwarf star. This planet orbits a little too far from the star, but the greenhouse effect would be enough to make this planet habitable. The other ocean planet candidate, GJ 1214 b, was detected by transit in which the density was calculated and determined that this planet is an ocean planet. Now disputed.
Gliese 12 b, which orbits a cool, red dwarf star located just 40 light-years away, promises to tell astronomers more about how planets close to their stars retain or lose their atmospheres. In ...
Gliese 581g / ˈ ɡ l iː z ə / was a candidate exoplanet postulated to orbit within the Gliese 581 system, twenty light-years from Earth. [9] It was discovered by the Lick–Carnegie Exoplanet Survey, and was the sixth planet claimed to orbit the star; [10] however, its existence could not be confirmed by the European Southern Observatory (ESO) / High Accuracy Radial Velocity Planet Searcher ...
Jeff Bezos’ rocket company Blue Origin is cutting 10% of its workforce. This week's move comes a month after the debut of Blue Origin’s New Glenn rocket, which reached orbit on its first try.
