The planet’s true size and density remain unknown, however, which means it could still turn out to be a gas planet, hostile to life as we know it. And powerful magnetic fluxes also could mean periodic drop-offs in the amount of energy reaching the planet, by as much as 40 percent. These drop-offs could last for months, according to scientists at the University of Oslo’s Institute of Theoretical Astrophysics in Norway." data-dst="不是所有的行星撞地球被发现是最喜欢利用开普勒。超级地球格利泽667cc也轻2011，天文学家通过梳理从欧洲南方天文台的3.6米望远镜在智利的数据发现。地球上，只有22光年，具有质量至少是地球的4.5倍。它围绕红矮星宜居带中，虽然不够紧密，仅仅28天的轨道，让地球遭受强烈的耀斑爆发，会周期性地从恒星的表面。不过，它的太阳比我们小冷，一颗667cc的轨道距离意味着它可能收到大约百分之90的能源我们从太阳得到的。这是有利于生活的一点，如果这颗行星的大气有点像我们。地球的真实大小和密度仍然是未知的，但是，这意味着它仍可以是气体行星，与我们所知道的生活。强大的磁场也可能意味着在能量到达地球周期性的峭壁，高达百分之40。这些下降可能持续几个月，科学家在挪威的奥斯陆大学的理论天体物理研究所。" style="box-sizing: border-box; background: transparent;">不是所有的行星撞地球被发现是最喜欢利用开普勒。超级地球格利泽667cc也轻2011，天文学家通过梳理从欧洲南方天文台的3.6米望远镜在智利的数据发现。地球上，只有22光年，具有质量至少是地球的4.5倍。它围绕红矮星宜居带中，虽然不够紧密，仅仅28天的轨道，让地球遭受强烈的耀斑爆发，会周期性地从恒星的表面。不过，它的太阳比我们小冷，一颗667cc的轨道距离意味着它可能收到大约百分之90的能源我们从太阳得到的。这是有利于生活的一点，如果这颗行星的大气有点像我们。地球的真实大小和密度仍然是未知的，但是，这意味着它仍可以是气体行星，与我们所知道的生活。强大的磁场也可能意味着在能量到达地球周期性的峭壁，高达百分之40。这些下降可能持续几个月，科学家在挪威的奥斯陆大学的理论天体物理研究所。</trans></p><p style="box-sizing: border-box; margin: 0px 0px 15px; -webkit-font-smoothing: inherit; line-height: 1.4em; font-family: \'Helvetica Neue\', Helvetica, Arial, sans-serif; background-color: rgb(255, 255, 255);"></p><p style="box-sizing: border-box; margin: 0px 0px 15px; -webkit-font-smoothing: inherit; line-height: 1.4em; font-family: \'Helvetica Neue\', Helvetica, Arial, sans-serif; background-color: rgb(255, 255, 255);"><trans data-src="Deduct two points." data-dst="扣两分。" style="box-sizing: border-box;">扣两分</trans></p><p style="box-sizing: border-box; margin: 0px 0px 15px; -webkit-font-smoothing: inherit; line-height: 1.4em; font-family: \'Helvetica Neue\', Helvetica, Arial, sans-serif; background-color: rgb(255, 255, 255);"></p><p style="box-sizing: border-box; margin: 0px 0px 15px; -webkit-font-smoothing: inherit; line-height: 1.4em; font-family: \'Helvetica Neue\', Helvetica, Arial, sans-serif; background-color: rgb(255, 255, 255);"><trans data-src="Too big, too uncertain, or circling the wrong kind of star: Shuffle through the catalog of habitable zone planets, and the closest we can come to Earth -- at least so far -- appears to be the new kid on the interstellar block, Kepler-452b." data-dst="太大，太不确定，或盘旋星错误：通过对可居住地带的行星目录洗牌，和最近我们能来到地球--至少到目前为止，似乎在星际块新的孩子，kepler-452b。" style="box-sizing: border-box; background: transparent;">太大，太不确定，或盘旋星错误：通过对可居住地带的行星目录洗牌，和最近我们能来到地球--至少到目前为止，似乎在星际块新的孩子，kepler-452b。</trans></p><p style="box-sizing: border-box; margin: 0px 0px 15px; -webkit-font-smoothing: inherit; line-height: 1.4em; font-family: \'Helvetica Neue\', Helvetica, Arial, sans-serif; background-color: rgb(255, 255, 255);"></p><p style="box-sizing: border-box; margin: 0px 0px 15px; -webkit-font-smoothing: inherit; line-height: 1.4em; font-family: \'Helvetica Neue\', Helvetica, Arial, sans-serif; background-color: rgb(255, 255, 255);"><trans data-src="NASA\'s Ames Research Center in Moffett Field, California, manages the Kepler and K2 missions for NASA\'s Science Mission Directorate.
