The Sun, Moon and Planets

The SUN, MOON and PLANETS

太阳、月亮和行星

Which matters most? Welcome to space- or at least, the tiny bit you live in. I'm a comet called Edmond. My journeys take me all around this area, so I know all the planets around the Sun. Rocky planets are those with a surface made of solid material. Gas giant and ice giant planets are made mostly of huge balls of fluid. The Sun and the planets all think they're important. For Earthlings, the Moon is also important. But which is the MOST important? Let's ask them and try to find out...

哪个最重要？欢迎来到太空——或者至少是你居住的那一小块地方。 我是一颗叫爱德蒙的彗星。 我的旅行带我走遍了这个地区，所以我知道太阳周围的所有行星。 岩石行星是表面由固体物质构成的行星。 气态巨行星和冰态巨行星主要由巨大的流体球组成。 太阳和行星都认为自己很重要。 对地球人来说，月球也很重要。 但是哪个是最重要的呢？ 让我们问问他们，试着找出答案……

The Sun The big, hot one I contain 99.9% of all the matter in the solar system! That gives me the strongest gravity around. If I wasn't keeping them here, the planets would go pinging off who knows where. Earth could end up being sucked into a black hole... ...or drifting into a field of asteroids. Without my heat and light, life on Earth would not be possible. Plants would not grow. Animals that eat plants could not survive. Humans would not have anything to eat. It would also be very, very cold. I hold the solar system together and provide the warmth that makes life on Earth possible. I MUST matter most.

太阳这个又大又热的太阳包含了太阳系中99.9%的物质！这给了我最强的引力。 如果我不把它们留在这里，行星就会发出不知道在哪的信号。 地球最终可能会被黑洞吞噬…… …或者漂流到小行星区。 没有我的光和热，地球上的生命就不可能存在。 植物不会生长。以植物为食的动物无法生存。 人类将没有东西可吃。 它也会非常非常冷。 我维系着太阳系，为地球上的生命提供温暖。 我必须是最重要的。

Mercury Hot... and cold Earth- foo! Earth takes a YEAR to orbit the Sun. I've done it four times by then! That's not the only thing about me that's different from Earth. Each day and night on me lasts nearly 59 Earth days. Imagine having to go to bed for half that! Goodnight listeners and see you in 29 days time. The Sun is so close that when it comes up, I get very, very hot. Inside temperature: 20°C Outside temperature: 450°C At least, it's hot at the surface. Most of the heat quickly escapes into space. At night, the sunshine disappears and suddenly it's MINUS 180°C. This is a very strange place. I'm never going there again! So, I THOUGHT I was pretty important- but it turns out that if you're from Earth, you might not agree.

汞热……寒冷的地球——喂！地球绕太阳公转一周需要一年。 到那时我已经做了四次了！这并不是我和地球唯一不同的地方。 我的每一天和每一夜都相当于地球上的59天。 想象一下，一半的时间都要躺在床上！各位听众，晚安，29天后再见。 太阳离我很近，当它升起的时候，我感到非常非常热。 内部温度：20°C外部温度：450°C至少表面是热的。 大部分热量很快逃逸到太空中。 到了晚上，阳光消失了，气温突然降到零下180°C。 这是一个很奇怪的地方。 我再也不去那里了！所以，我认为我很重要——但事实证明，如果你来自地球，你可能不同意。

Venus Greenhouse gone wrong This is so exciting! I'm in a book! It's making me feel all hot and bothered! People sometimes call me 'Earth's twin'- and it's true because... ...we're almost the same size and we both have mountains and volcanoes on the surface. We're not THAT alike, though. My thick atmosphere traps a lot more heat from the Sun- making me the solar system's hottest planet. My atmosphere is not very welcoming to humans. Venus's greenhouse effect. Sun's heat Layers of gas Heat trapped Even though they wouldn't like it here, I still matter to Earthlings. I show them what can happen when a greenhouse effect gets out of control! Atmosphere of Venus (not very welcoming) Space Mist of sulphuric acid drops (poisonous) More sulphuric acid mist (more poisonous) Sulphuric acid drops and dust (poisonous) Carbon dioxide (poisonous)

金星温室出了问题这太令人兴奋了！我在书里！这让我觉得又热又烦！人们有时称我为“地球的孪生兄弟”——这是真的，因为…… …我们的大小几乎一样，我们的表面都有山脉和火山。 不过，我们并没有那么相像。 我厚厚的大气层吸收了更多来自太阳的热量，使我成为太阳系最热的行星。 我的大气层不太欢迎人类。 金星的温室效应。 太阳的热量层的气体热量被困即使他们不喜欢这里，我仍然对地球人很重要。 我向他们展示当温室效应失控时会发生什么！金星大气（不太受欢迎）太空硫酸滴雾（有毒）更多硫酸雾（更有毒）硫酸滴和灰尘（有毒）二氧化碳（有毒）

Earth Home Obviously I'm the most important planet, because I'm where you live! I'm the right distance from the Sun for it to be warm, but not too hot. Surface temperature 5,500°C Everything about me is just perfect for humans (and other living things, too). There is a surface to stand on, unlike the gas giant planets (on pages 18-25). Sunlight travels through space to Earth Average temperature 14.74°C There's air to breathe and plenty of water (unlike any of the other planets). Sometimes too much water... I like it! Me too. The only problem is that I'm getting hotter. The more greenhouse gases humans release, the hotter I get. The extra heat is causing all sorts of problems, like floods and droughts.

地球之家显然我是最重要的星球，因为我是你生活的地方！我和太阳的距离正好，既温暖又不会太热。 我身上的一切对人类（以及其他生物）来说都是完美的。 它有一个可以站立的表面，不像气态巨行星（见18-25页）。 阳光穿过太空到达地球平均温度14.74°C，有空气可以呼吸，有充足的水（不像其他任何行星）。 有时水太多…… 我喜欢！我也是。唯一的问题是我越来越热了。 人类排放的温室气体越多，我就越热。 额外的热量造成了各种各样的问题，比如洪水和干旱。
