An international team of scientists found the planet moving around the star called "Proxima Centauri".

一个国际科学家团队发现这颗行星围绕着被称为“比邻星”的恒星运行。

The nearest star to our own is Proxima Centuari and it lays just over 4 light-years away.

离太阳最近的恒心是半人马座（即比邻星），它与太阳相距4光年。

The nearest star, Proxima Centauri, has a planet orbiting it not much bigger than Earth.

有一颗大小与地球相近的行星围绕着距离太阳最近的恒星——半人马座比邻星运转。

The next-closest known star to the Sun is Proxima Centauri, located 4.2 light years away.

距太阳第二近的恒星是比邻星，距离为4.2光年。

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。

Moreover, given ingenious mission design, it might be possible to visit the nearby red dwarf star Proxima Centauri as well.

不仅如此，若项目设计精妙，它可能也能访问附近的红矮星比邻星。

Thus Proxima b, despite its closeness to the star, receives less warmth than Earth, but enough that water could flow on the surface.

因此，尽管Proxima b与比邻星距离很近，但接收的热量要小于地球，却又足以保留水在其表面流动的可能性。

From the size of the wobbles, the astronomers determined that Proxima bis at least 1.3 times the mass of Earth, although it could be several times larger.

通过这种移动的大小，天文学家们确定Proxima b的质量至少是地球的1.3倍，尽管它也可能要大上好几倍。

The third star, a red dwarf called Proxima Centauri, circles this couple at a considerable distance and is too faint for Fischer's team to study, but it could boast small planets, too.

第三颗被称作比邻星的红矮星，在相当远的距离之外绕这两颗恒星旋转，由于亮度太弱费希尔的团队无法对其进行研究，不过它也可能拥有质量较小的行星。
