Le système Gliese 581 se trouvant à environ 20,5 années-lumière de … asserted that if Gliese 581c has an Earth-type composition, it would have a radius of 1.5R ⊕, which would have made it at the time "the … also points out that when the red dwarf was a strong X-ray and EUV emitter, planet surface temperatures would range from 700 K to 1000 K (430 to 730 °C), like Venus today. Gliese 581d is the third planet from its host star in the Gliese 581 system, or the fifth planet if you include two unconfirmed planets. A Message from Earth (AMFE) is a high-powered digital radio signal that was sent on 9 October 2008 towards Gliese 581 c, a large terrestrial extrasolar planet orbiting the red dwarf star Gliese 581. 1. The super-Earth Gl 581c is clearly outside the pHZ, while Gl 581d is at the outer edge of the pHZ. グリーゼ581cは、太陽系から約20光年離れた赤色矮星、グリーゼ581の周囲を公転する太陽系外惑星である。 この星系の惑星としては2番目に発見され、内側から数えて第3惑星にあたる。. グリーゼ581cは、初めて発見された ハビタブルゾーン 内に存在する地球型の惑星とされたため、天文学者達から多くの関心を集めた 。.
