关于流星的15个小秘密

[复制链接]

1.The most famous and spectacular meteor shower, the annual Perseids, will peak on August 12th.

一年一度的英仙座流星雨是最著名、最壮观的流星雨,一般在8月12日达到高峰。

2.The Perseids are also called the "Tears of Saint Lawrence" after a martyred Christian deacon whom the Romans burned to death on an outdoor iron stove in A.D. 258.

英仙座流星雨也被称作“圣劳伦斯之泪”。这个称呼来源于公元前258年被罗马人烧死在大铁炉里的基督教殉道者圣劳伦斯。

3.Technically, a meteor is merely the streak of light we see trailing a meteoroid. A meteoroid is any interplanetary object bigger than a speck of dust and smaller than an asteroid.

严格说来,“流星”仅仅指“流星体”身后的那一道光,也就是我们看着划过天空那一道。而“流星体”则可以是太阳系内任意一个比尘埃大但比小行星小的天体。

4.Once it hits Earth, a meteoroid suffers an identity crisis and becomes a meteorite.

流星体一旦撞上地球,就变成了“陨石”。

5.Chase that, Superman: Perseid meteoroids enter the atmosphere at approximately 130,000 miles per hour.

英仙座流星雨的流星体进入大气层的速度约为130,000英里/时(209,215公里/时)。

6.Meteorites contain the oldest known rocks in the solar system, as well as minerals that formed around other stars perhaps billions of years before our solar system was born.
