Turns out that anything less massive than one trillion suns is very unlikely.

事实证明，银河系的重量不可能少于一万亿个太阳。

It takes a whole year for the Earth to go around the sun one time.

地球围绕太阳公转一周需要一年。

And there's only one sun in our solar system.

在我们的太阳系中只有一个太阳。

Now all we have to do is make the sun one percent dimmer.

现在我们所要做的就是让太阳变暗百分之一。

Chances would be high that an alien star would collide with our Sun one day.

有一天，一颗外星恒星与我们的太阳相撞的可能性很高。

And there were two tiny spots of sun, one on the inkpot, one on a silver photograph frame, playing too.

还有两个小太阳， 一个在墨水瓶上， 一个在银色相框上， 也在玩耍。

Well, normally I'd put on a festive hat and celebrate the fact that the earth has circled the sun one more time.

嗯 通常 这是我的节日 标志着地球又绕太阳转了一圈。

However, while the Earth takes about 365 days to travel once around the sun—one year—the moon completes its orbit around the Earth in only 29 and a half days—or about one month.

但是地球绕太阳转一圈要365天，也就是一年，月球绕地球公转只要29天半，大概一个月。

And when we’re at our closest point to the Sun, one day’s worth of the orbit will sweep out an area that’s more like a short, fat pizza slice.

当我们到达离太阳最近的点时，一天的轨道将扫过一个更像是一块又短又肥的比萨饼的区域。
