英语翻译
Our sun is a star,and nine worlds (星球) move around it.World like these are planets.But there are other stars,other suns.Not only thousands of them,but millions of them.Do other stars have planets?We can see the planets round our own sun.But we haven’t seen any more.The stars are too far away from us.Stars give out light,but the planets don’t have any light of their own.So we can’t see them.They are too far,and too dark.
Still,we can tell that some stars have planets.While a big planet goes round,it pulls its star to one side.And sometimes we can see this.Then we know that the star has a planet.
For example,Barnard’s Star is a small red star.And it is the quickest star in the universe.But sometimes it moves slower,and then quicker again.We have known Barnard’s Star for many years,and now we are sure it has a planet.

我们的太阳是颗恒星,有九个星球围绕它转动.这些星球就是行星.此外还有其他很多像太阳一样的恒星.他们的数量成千上万有很多很多.其他恒星也有行星围绕么?我们可以看到行星在绕着我们的太阳转.但是,我们没有看到其他的恒星也有这种现象.那些恒星距离我们太遥远了.恒星发射出光,但是行星却不会自己发光.所以,我们无法观测到其他行星.他们太远也太暗.
不过,我们可以说一些恒星有行星.当一个巨大的行星旋转时,它拉动它的恒星到另一边.这些我们有时可以观测到.因此,我们知道那个恒星有一颗行星.
举例来说,伯尔纳德恒星是一颗小的红色星球.它也是宇宙中移动最快的恒星.但是有时它的移动会慢下来,然后再快起来.我们已经了解伯尔纳德恒星不少年了,并且我们相信它有一颗行星.
