Oh, hey, Squeaks! You're up early!
哦，嘿，吱吱，你今天很早啊！
Oh… the Sun woke you up, and you couldn't get back to sleep?
哦……太阳把你吵醒了，所以你睡不着？
That happens to me sometimes, too! The Sun is shining really brightly out there!
我有时也会这样！外面的太阳真的很亮！
But on the bright side, it's going to be a perfect day for our hike around the Fort!
但往好的方面想，这个天气非常适合我们在“城堡”附近徒步！
Yeah, that's the spirit! You know, we don't often think about the Sun…
对，就是这种精神！你知道，我们一般不会想到太阳……
You're right - unless it's shining right in our faces. But it makes you think: What is the Sun, really?
没错，除非太阳直射到你脸上。但这也会让你陷入思考：太阳到底是什么？
Hey, did I hear someone ask a question about the Sun?
嘿，我听到有人问关于太阳的问题了？
Oh, hi, Sam! Our friend Sam the Bat is calling from the fort's observatory!
哦，嗨，山姆！我们的朋友蝙蝠山姆从"堡垒"的天文台打来电话！
Sam is a bit of an astronomer, which means he's someone that studies astronomy.
萨姆有点天文学家的味道，也就是说他是研究天文学的。
Astronomy is the study of things that are in space — things like other planets… the Moon... and the stars! Stars like Earth, Sun!
"天文学"是研究太空里的事物的学科，比如其他行星，月亮、星体，像地球、太阳这样的星体。
Yup, the Sun is a star… just like the ones you might be able to see in the sky at night. And it's the center of our solar system.
是的，太阳是一颗星体，就像晚上在天空中看到的星星一样，它是太阳系的中心。
That's the part of space we live in, and it includes the Sun, and all the planets that travel around it — like Earth!
太阳系是我们所生活的空间的一部分，其中包括太阳以及所有围绕它运行的行星——比如地球！
In fact, the Earth takes about 365 days to go all the way around the Sun… In other words, it takes one year!
事实上，地球绕太阳一周大约需要365天。换句话说，需要一年的时间！
So, if you're six years old, that means the Earth has gone around the Sun six times since you were born! Cool!
所以，如果你六岁，那就意味着从你出生起地球已经绕着太阳转了六圈！太酷了！
And what's even cooler about the Sun is how hot it is!
太阳更酷的地方在于，它非常热！
...well, maybe "cooler" isn't the best word. But it's really interesting! Like all stars, our Sun is a ball of burning gases.
……嗯，也许用“更酷”这个词形容不太合适，但是真的很有趣！像所有的恒星一样，我们的太阳也是一个燃烧的气体球。
You're right, Squeaks! There are also gases here on Earth, like in the air that we're breathing right now.
没错，吱吱！地球上也有气体，就像我们现在呼吸的空气一样。
But the gases on Earth are a lot colder than the ones in the Sun.
但是地球上的气体比太阳上的要冷得多。
Right! The gases in the Sun are really hot, and they make light, and heat — lots of it!
没错！太阳中的气体非常热，它们产生光和热——大量的光和热!
How hot is the Sun? Well, imagine you're playing outside on a warm, summer day.
太阳到底有多热？嗯，想象一下，在一个温暖的夏日，你正在外面玩耍。
It's about 27 degrees Celsius, or 80 degrees Fahrenheit, and you feel a little hot and sweaty.
温度大约是27摄氏度，或80华氏度，你会感到有点热，出汗了。
Well, the surface of the Sun is about 5700 degrees Celsius, or more than 10 thousand degrees Fahrenheit!
嗯，太阳表面大约是5700摄氏度，或超过1万华氏度！
That's really, really hot! Anything that gets too close to the Sun would burn up!
那真的，真的很热！任何离太阳太近的东西都会被烧掉！
It's true! And the Sun's not only hotter than Earth. It's a lot wider than Earth… over one hundred times wider!
是这样！太阳不仅比地球热，它还比地球大得多……大了一百多倍！
Oh, good idea, Squeaks! We can make a model that shows what "one hundred times wider" looks like!
哦，好主意，吱吱！我们可以制作一个模型，显示出“大一百倍”的样子！
We use models to help us understand or explain something in the world around us.
我们用模型来帮助我们理解或解释我们周围世界的一些东西。
We can use a ball or other toy to be a model of a planet.
我们可以用一个球或其他玩具来做行星的模型。
So with a model, we can use some things we found around the Fort to show how big the Sun is compared to the Earth!
所以有了模型，我们就可以用我们在“堡垒”周围发现的一些东西来展示太阳和地球相比有多大！
Good idea! Astronomers use models all the time.
好办法！天文学家也一直在使用模型。
So let's use this pin to represent Earth in our model.
我们用这个大头针来代表模型中的地球。
If the Earth was the size of the end of this pin — which is pretty small! — the Sun would be about the size of this basketball. That's a big difference!
如果地球只有这枚大头针的末端那么大——它非常小！那么太阳大概就有这个篮球那么大。真的相差太多了！
It is! But, you know, the Sun is actually only kind of medium-sized when you compare it to other stars.
是的！但是，你知道，太阳和其他行星比较时其实只是中等大小。
Like, red dwarf stars are smaller than our Sun. In fact, they're some of the smallest stars in space!
比如，红矮星比太阳小。其实，它们是太空中最小的行星！
On our model, they would only be about as big as a postage stamp.
在我们的模型中，它们只有一张邮票那么大。
Then, there are supergiant stars. Like the name says, those are… super giant!
然后，还有超巨星。就像它的名字一样，它们超级大！
They're over a thousand times wider than our Sun! In our model, a star like that would be as wide as a skyscraper is tall!
它们比太阳大一千多倍！在我们的模型中，像这样的星星会有摩天大楼那么高！
Whoa, we'd need a bigger Fort to hold that model!
哇哦，我们需要一个更大的“堡垒”来支撑那个模型！
Oh, good question. Squeaks said that he's seen pictures of the Sun, and it looks much bigger than the stars he sees in the night sky.
哦，问得好。吱吱说他看过太阳的图片，看起来比他在夜空中看到的星星要大得多。
So, why is that? If other stars are actually much bigger than the Sun, why do they look so small?
所以，为什么呢？如果说其他行星实际上要比太阳大得多，那为什么它们看起来这么小呢？
That's because the Sun is the closest star to Earth!
那是因为太阳是离地球最近的行星！
Other stars are so far away that even in our fastest rocket, it would take thousands and thousands of years to get there.
其他行星非常遥远，即便用我们最快的火箭也要花上几千年才能达到那里。
But the Sun is much closer! I mean… it's still about 150 million kilometers away, which is pretty far.
但是太阳离我们近得多！不过，即便如此，它距离地球还是有1.5亿公里那么远。
That means if you tried to drive to the Sun at the same speed as you can drive on a highway, it would still take you over 170 years to get there!
这意味着，如果你想以高速公路上一样的速度驶向太阳，那么你仍需170年才能到达那里！
But it turns out that this distance is pretty perfect for our planet.
不过事实证明，这个距离对我们的星球来说是相当完美的。
The Sun's heat and light make it possible for all sorts of plants and animals — including us — to live on the Earth.
太阳的光和热给了包括我们在内的各种植物和动物在可以在地球上生活的条件。
Any closer, and the Earth would be too hot. If it were any farther away… it would be too cold!
再近一点，地球就太热了。如果再远一点……就太冷了！
It's just like the story Goldielocks and the Three Bears! As stars go, our Sun is just right.
就像《金发姑娘与三只熊》的故事一样！随着行星的移动，太阳的位置正好合适。
And you know one more thing about the Sun? When it comes up, it's time for bats like me to go take a nap.
还有一件关于太阳的事情要告诉你，就是当太阳出现时，像我这样的蝙蝠就该去打盹了。
Hope you and Squeaks have fun in your hike today. Bye!
希望你和吱吱今天能有一个愉快的徒步旅行，拜！
Thanks, Sam! And thank you for joining us here today! It was so fun to have Sam the Bat over to tell us more about the Sun.
谢谢，山姆！谢谢你今天的加入！让蝙蝠山姆来告诉我们更多关于太阳的事情真是太有趣了。
