这个观点推翻了之前的理论，即小行星和彗星的碰撞纯粹是一种破坏性的过程，以为月壳是由月球内部上升的岩浆形成的。

The idea overturns previous theories that colliding asteroids2 and comets were a purely3 destructive process with the lunar crust being created by magmas rising from the interior .

我给你们讲关于小行星B612的这些细节，并且告诉你们它的编号，这是由于这些大人的缘故。这些大人们就爱数目字。

If I have told you these details about the asteroid , and made a note of its number for you , it is on account of the grown-ups and their ways .

但是，如果你对他们说：“小王子来自的星球就是小行星B612”，那么他们就十分信服，他们就不会提出一大堆问题来和你纠缠。

But if you said to them : " The planet he came from is Asteroid B-612 , " then they would be convinced , and leave you in peace from their questions .

当一个天文学者发现了其中一个星星，他就给它编上一个号码，例如把它称作“325小行星”。

When an astronomer1 discovers one of these he does not give it a name , but only a number . He might call it , for example , " Asteroid2 325 . "

在附近的宇宙中，还有325、326、327、328、329、330等几颗小行星。他就开始访问这几颗星球，想在那里找点事干，并且学习学习。

He found himself in the neighborhood of the asteroids1 325 , 326 , 327 , 328 , 329 , and 330 . He began , therefore , by visiting them , in order to add to his knowledge .

我从来不大愿意以道学家的口吻来说话，可是猴面包树的危险，大家都不大了解，对迷失在小行星上的人来说，危险性非常之大，因此这一回，我贸然打破了我的这种不喜欢教训人的惯例。

I do not much like to take the tone of a moralist . But the danger of the baobabs is so little understood , and such considerable risks would be run by anyone who might get lost on an asteroid9 , that for once I am breaking through my reserve .
