Shoot for Mars or Alpha Centauri.

向火星或半人马座阿尔法星发射。

Wait 'til the Centauri see this.

让人马兽看看这个。

It orbits a red dwarf star called Proxima Centauri in a system with three stars in it.

它在一个三星系统里围绕着一颗名为比邻星的红矮星运动。

We're charged and aimed at Alpha Centauri, ready for transport.

已经充电，瞄准了半人马阿尔法星，准备传送。

But in fact, as Klein later admitted, the picture was not of Proxima Centauri.

但事实上，正如克莱恩后来承认的那样，这张照片并不是半人马座比邻星。

Consider the case of Proxima Centauri, the closest star after the Sun.

以比邻星为例，它是离太阳最近的恒星。

Is Proxima Centauri REALLY the closest star, or will we find one even closer?

比邻星真的是离我们最近的恒星吗，或者我们会找到更近距离的恒星吗？

The nearest star to the sun we know of, Proxima Centauri, is about 4.2 light years away.

据我们所知，距离太阳最近的恒星是比邻星(Proxima Centauri)，距离我们大约4.2光年。

As well as a planet called Proxima b, orbiting Proxima Centauri, a mere 4.2 light-years from us.

同时，他们还发现了围绕半人马座比邻星运行的比邻星b，而那里距我们仅有4.2光年。

It takes stars like Proxima Centauri much longer to burn through all of their hydrogen supply.

所以比邻星要过更久，才会耗尽它所有氢供应。
