【火狐体育】NASA on Thursday announced the discovery of Kepler-452 b,the most Earth-like planet ever found . located 1,400 light-yes Nasa caller周四,美国国家航空航天局(以下简称NASA)宣布找到开普勒-452b,这是迄今为止与地球特别相似的行星。这颗行星距离地球1400光年,NASA将其命名为“地球2.0”。这是因为它是在人适合居住的地区靠近太阳的星星附近发现的第一颗行星。

we can think of Kepler-452 b as an older,bigger cousin to earth,providing an opportunity to understand and reflect upon earths evolvinving“开普勒-452b可以看作是地球年龄小、体积小的‘老牌’。从中我们可以理解和反思地球进化的环境。”NASA Ames研究中心开普勒数据分析的领导者约翰詹金斯说。

the planet is 5 percent farther away from its star than earth is to the sun,making for a slightly longer year of 385 days,but gets similar light因为星星的亮度比太阳低20%。the sunshine from this star would feel very similar to the sunshine from our star,Jenkins told reporters。詹金斯对记者说:“开普勒-452b的阳光和我们火狐体育直播地球的阳光相似。

”NASA believes the planet has a mass about five times more massive than earths,With a rocky surface below a thicker atmosphere than our own。据Gravity would be about twice as strong on Kepler-452 b as it is on earth,NASA NASA称,该行星的质量大约是地球的5倍,岩石表面的海平面大气层比地球的大气层薄得多。

开普勒-452b的重力是地球重力的两倍。the planet is located in the Kepler-452 system in the constellation cygnus . its sun has the same surface temperature as our own,but has a那个行星是开普勒它的恒星表面温度与地球相同,但直径比地球大10%。while NASA scientists have no idea if Kepler-452 bs atmosphere is conducive to life,they do know that there has been plenty of time for organiiits awe-inspiring to consider this planet spent 6 billion years in the habitable zone of its star,which is longer the age of the earth,Jenkins“这个行星在恒星的居住地已经不存在60亿年了。

这个汉密尔顿地球的年龄要大得多。看着真可怕。”詹金斯说。

“如果这个星球上没有生命存在的所有必要条件,这个时间就不足以在它的表面形成生命。。
