Rachel Crane explains why our nearest star is so mysterious.

雷切尔·克兰解释了为什么离我们最近的恒星如此神秘。

And the vehicle that's headed to our nearest star is named the Parker Solar Probe.

这次发射到距我们最近恒星的运载火箭被命名为帕克太阳探测器。

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。

Yes, that’s right. The sun is our nearest star – although it’s a staggering 150 million kilometres away.

对。虽说太阳距离我们有1.5亿千米之遥，但它是距离我们最近的恒星。

After all this dreaming for millennia, it turns out our very nearest star to our sun has a planet.

在经历了数千年的幻想之后，我们发现离太阳最近的恒星有一颗行星。

As it exhausts its hydrogen fuel, our nearest star will cool and gradually collapse under the force of gravity.

随着氢燃料的耗尽，这颗离我们最近的恒星会冷却下来，在引力作用下逐渐崩塌。

Klein wrote on Twitter that the object was a Webb-captured image of Proxima Centauri, the nearest star to the sun.

克莱恩在推特上写道，该天体是韦伯拍摄的半人马座比邻星的图像——比邻星是距离太阳最近的恒星。

The nearest star to the Sun is a red dwarf called Proxima Centauri, which orbits the binary star Alpha Centauri.

距离太阳最近的恒星是一颗被称为比邻星的红矮星，它围绕着半人马座阿尔法双星运行。

Scientists hope projects like this will help them better understand Earth's nearest star and better predict space weather and solar storms.

科学家希望这样的项目能够帮助他们更好地了解这颗离地球最近的星球，并预测太空气象和太阳风暴。

The nearest star that might explode in this way is Spica, in Virgo, and it's well over 100 light years away.

距我们最近的可能以这种方式爆炸的恒星是室女座的 Spica，它离我们有100光年远。

There's not a planet in our solar system that could sustain life and the nearest star's over a thousand years away.

太阳系没有适合人类生存的星球，系外最近的行星却在一千光年之外。

We have a payload to deliver to the heart of our nearest star.

我们有一个有效载荷可以运送到距离我们最近的恒星的中心。

It's called Proxima B. It apparently orbits the nearest star to our sun.

它被称为 Proxima B。它显然围绕离我们太阳最近的恒星运行。

The nearest star system to us is Alpha Centauri, 4.3 light years away, so we see it as it was 4.3 years ago.

离我们最近的恒星系统是半人马座阿尔法星，距我们4.3光年，所以我们看到的它是4.3年前的样子。

When going in that speed will still take about 19,000 years to just reach Proxima Centauri — the nearest other stars to the Sun.

当以这样的速度前进时，仍然需要大约 19000 年才能到达比邻星——离太阳最近的其他恒星。

A more powerful version could cross the vast void to Alpha Centauri, the nearest star to the sun, in a bit over a century.

一个更强大的火箭可能在一个多世纪后穿过这片巨大的空间，到达离太阳最近的半人马座阿尔法星。

You will find that there is no significant difference between the velocities of stars near the galaxy's center compared to those much farther away.

你会发现，靠近星系中心的恒星的速度与那些远得多的恒星的速度没有显著差异。

Flares and ejections from our nearest star didn't have any impact on satellites, global positioning systems, astronauts, mainly because none of those things existed.

离我们最近的恒星发出的太阳耀斑和日冕物质抛射对人造卫星、全球定位系统和宇航员都不会产生任何影响，主要是因为那时这些东西都不存在。

However, if we reach this goal, it will still take 4 years to reach the nearest star to our sun.

然而，如果我们达到这个目标，仍然需要 4 年的时间才能到达离我们太阳最近的恒星。

That would enable us to get to the nearest star, Proxima Centauri, which is a little over four light years away, in less than 20 years.

这将使我们能够在不到 20 年的时间内到达最近的恒星 Proxima Centauri，它距离我们四光年多一点。
