太空矮人介绍英文作文
英文：
Space dwarfs, also known as brown dwarfs, are celestial bodies that are too small to be classified as stars but too large to be considered planets. They are often referred to as "failed stars" because they are not massive enough to sustain nuclear fusion in their cores, which is what powers stars.
These objects are typically around 13 to 80 times the mass of Jupiter and have temperatures ranging from 300 to 2,500 Kelvin. They emit very little visible light, but they do emit infrared radiation, which can be detected by telescopes.
One interesting fact about space dwarfs is that they can have atmospheres, just like planets. In fact, some space dwarfs have been found to have water vapor, methane, and other gases in their atmospheres. This has led
scientists to speculate that space dwarfs could potentially support life, although this is still just a theory.
Another interesting thing about space dwarfs is that they can have moons. In 2018, a team of astronomers discovered a moon orbiting a space dwarf located 8,000
light-years away from Earth. This was the first time a moon had been discovered around a space dwarf.
Overall, space dwarfs are fascinating objects that are still being studied and understood by scientists. As technology advances and telescopes become more powerful, we will undoubtedly learn even more about these mysterious celestial bodies.

太空矮人，也被称为棕矮星，是一种太空天体，太小无法被归类为恒星，但太大也无法被视为行星。

它们通常被称为“失败的恒星”，因为它们的质量不足以在其核心维持核聚变，这是恒星的动力来源。

这些物体通常约为木星质量的13至80倍，温度在300至2500开尔文之间。

它们发出的可见光非常少，但它们确实会发出红外辐射，可以被望远镜探测到。

关于太空矮人的一个有趣事实是，它们可以像行星一样拥有大气层。

事实上，一些太空矮人已被发现拥有水蒸气、甲烷和其他气体的大气层。

这导致科学家推测，太空矮人有可能支持生命，尽管这仍然只是一个理论。

太空矮人的另一个有趣之处是，它们可能会有卫星。

2018年，一组天文学家发现了一颗卫星绕着一个距离地球8000光年的太空矮人运转。

这是首次发现绕太空矮人运转的卫星。

总的来说，太空矮人是令人着迷的天体，科学家们仍在研究和理解它们。

随着技术的进步和望远镜的更加强大，我们无疑会了解更多这些神秘的天体。
