GJ 581d is believed to be the first planet outside our solar system in the Goldilocks zone around its star an area not too hot and not too cold for life.

GJ581d被认为是在太阳系之外宜居带内发现的绕恒星运动的第一颗行星。宜居带不冷不热，适合生命生存。

If confirmed, the exoplanet, named Gliese 581g, would be the first Earth-like world found residing in a star's habitable zone-a region where a planet's temperature could sustain liquid water on its surface.

如果得以证实，这颗被命名为“Gliese581g”的系外行星将成为第一颗类似地球的世界——该行星的温度可维持表面存在液态水。

NASA's Kepler Mission has discovered the first near-Earth-size planet orbiting in the habitable zone of a star very similar to our Sun.

NASA的开普特太空望远镜发现了首颗与地球大小近似并绕一颗类似太阳的恒星运行的行星。

In some ways, this Earth would resemble one of the tidally locked exoplanets commonly found in a red dwarf star's habitable zone, but a better comparison might be a very early Venus.

从某种角度来说，此时的地球会与那些潮汐锁定的地外行星类似——这样的行星常见于红矮星宜居带里，但更好的比较对象也许是非常早期的金星。

But it's in the habitable zone because Proxima Centauri is a red dwarf star about 100 times fainter than the sun.

但因为比邻星是一颗红矮星，它比太阳暗100倍左右，因此行星位于宜居区。

Located 1400 light-years from our planet, NASA called it "Earth 2.0," because it's the first planet discovered in the habitable zone of a G star similar to our sun 。

该行星距离地球1400光年，NASA将其命名为“地球2.0”，因为它是第一颗人类在宜居带里与太阳相似的恒星附近发现的行星。
