欧洲南方天文台于美国东部时间4月24日公布了新发现的行星“Gliese 581 c”围绕红矮星“Gliese 581”运转的模拟图。天文学家认为，这颗行星可能适合 ...

模拟图的灰色球体为新发现的疑似宜居星球。红色星球被称为红矮星Gliese 581，类似于太阳系中的太阳，但比太阳小得多，温度低得多。 Gliese 581c行星 ...

But Gliese 581 c and d could very well be big icy planets, with a very different composition from the Earth. [2] The team led by F. Selsis (CRAL and LAB, France) includes J.F. Kasting ...

Both teams found that, while Gliese 581 c is too close to the star to be habitable, the planet Gliese 581 d might be habitable. However, the environmental conditions on planet d might be too harsh ...

Gliese 581 is a red dwarf located 20.5 light-years from Earth, in the constellation Libra. Like other red dwarfs, it's smaller and much dimmer than our sun.

At that pace, it would take 766,000 years to get to Gliese 581 g—that’s more than three times longer than homo sapiens have been around. Even if we had the technology to go faster, the energy ...

Following the latest estimation, Gliese 581 would be 7 Gyr-old. The purple bars surrounding planets Gliese 581 c and d illustrate the variable distance to the star caused by the eccentricity of ...

Gliese 581c is a super-Earth planet that was discovered in 2007. It resides in the Gliese 581 system, which at 20 light-years from Earth is relatively close to our planet (in celestial terms).

Gliese 581 d is seven times as heavy as the Earth, which puts it in the class of the so-called super-Earth planets. There is every indication that because of the massive rocky planet, ...
