kepler-452b

The planet , called Kepler-452b , is about 60 percent larger than Earth .

这颗名为开普勒452-b的行星体积约比地球大60%。

The host star of Kepler-452b is the same " G " type as our Sun .

开普勒452-b的主星和太阳一样，是G级亮度的恒星。

Gravity would be about twice as strong on Kepler-452b as it is on Earth , NASA said 。

而开普勒-452b的引力是地球引力的2倍。

Kepler-452b receives only 10 percent more energy from its star than the Earth does from the Sun .

与地球从太阳那里得到的能量相比，开普勒452-b从它的主星得到的能量只多出10%。

Still , Kepler-452b 's star is much more Sunlike , which is certainly interesting .

而同样有趣的是，开普勒-452b所环绕的恒星和太阳类似。

NASA on Thursday announced the discovery of Kepler-452b , the most Earth-like planet ever found .

周四，美国国家航空航天局（以下简称为NASA）宣布发现开普勒-452b，是迄今为止与地球最为相近的行星。

For a while , Kepler-452b was known for being the closest to Earth 's size . That honor now goes to Kepler-186f .

有段时间，开普勒-452b以体积最接近地球而闻名，而现在，开普勒-186f获此殊荣。

Even so , scientists have confirmed that Kepler-452b is located in its star 's habitable zone , along with several companion exoplanets .

即便如此，科学家也证实了开普勒-452b和几颗系外伴星均位于其恒星的宜居带。

While NASA scientists have no idea if Kepler-452b 's atmosphere is conducive to life , they do know that there has been plenty of time for organisms to develop 。

虽然NASA的科学家们无法确定开普勒-452b的大气环境是否有利于生命的形成，但他们知道在该星球上有足够的时间来形成微生物有机体。

According to NASA , Kepler-452b could be " one of the best ( places ) to find extraterrestrial life . " This exoplanet , however , may prove to be difficult to explore . It 's over 1000 light-years away .

据美国宇航局资料显示，开普勒-452b可能是“最有机会找到外星生命的地方之一”。然而，这颗星球距地球超过1000光年，因此对这颗系外行星进行探索可能十分困难。
