冥王星是在最近一次的天文学大会上被踢出九大行星之列的。
引子：在经过激烈的讨论之后，国际天文学联合会大会24日上午公布了行星定义决议草案的最终版本。现在太阳系的天体包括：八大行星，矮行星和小天体。（探索频道将为您进行跟踪报道）
最新消息：天文学大会确认太阳系只有8颗行星
快讯：放弃将冥王星之外的太阳系八大行星称为“经典行星”的说法，从而确认太阳系只有8颗行星，冥王星遭到“降级”。"卡戎"将不被考虑赋予任何特殊的名称，而编号为"2003UB313"的天体和谷神星将和冥王星一起被定义为矮行星。"2003UB313"的天体的发现者美国加州理工学院天文学家布朗称："公众不会因为冥王星被踢出行星行列而感到惊讶。"他称这个结果为一次科学的决定。

3. 宇宙行星英语作文
宇宙，是我们所在的空间，“宇”字的本义就是指“上下四方”。
球是我们的家园；而地球仅是太阳系的第三颗行星；而太阳系又仅仅定居于银河系巨大旋臂的一侧；而银河系，在宇宙所有星系中，也许很不起眼…… 这一切，组成了我们的宇宙： 宇宙，是所有天体共同的家园。宇宙，又是我们所在的时间，“宙”的本意就是指“古往今来”。
因为，我们的宇宙不是从来就有的，它也有着诞生和成长的过程。现代科学发现，我们的宇宙大概形成于二百亿年以前。
在一次无比壮观的大爆炸中，我们的宇宙诞生了！（这就是著名的“大爆炸”理论。）宇宙一经形成，就在不停地运动着。
科学家发现，宇宙正在膨胀着，星体之间的距离越来越大。 宇宙的明天会怎样？许多的科学家正为此辛勤工作着。
这也许永远是一个谜，一个令人无限神往的谜 加上这些 太阳离我们究竟有多远？宇宙到底有多大？外星人真的光临过地球吗？……面对广阔，美丽而又神秘的宇宙空间，我带着好奇的渴望，提出了一个又一个被我困扰已久的问题。 自从读了这本《千万个为什么》以后，我的脑海里失去了许多问号。
书中的知识都是我最想知道的。每读一个故事，我都陶醉在其中，就好像在太空中飘浮，感受着宇航员的生活。
，你也可以投稿 外星人是否存在？是我觉得最有趣儿的问题，现在，这个迷团终于解开了。答案是：外星人存在。
因为，银河系中有那么多星体，而科学家发现，在银河系里，有一半的星体是存在生命的，所以外星人一定存在。但外星人有没有光临过地球，到现在还是一个未解之迷。
其实，宇宙并不像我们想象的那样神秘，它现在还是一个未解之迷，但我坚信，总有一天，它会变成一个被人们了解地非常清楚的宇宙。我眼中的世界处处新奇，时时新鲜，无数奇奇怪怪的“为什么”伴随着我进入更多未知世界！虽然仍有很多问号，但我渐渐地提高了理解力，思维力和创造力，我也会把剩下的问号变成句号。
4. 我要一篇关于宇宙几个行星的英文作文,初一水平就好
Our universe, mysterious, in our solar system, the study of value, as the universe. Now, let's see, members of the solar system. The planet mercury, a phrase, nor, even a drop of surface temperature is quite large, if you put in the daytime is a pig, KaoRuZhu, night is frozen pork. Venus, and mercury, on the contrary, it is extremely thick atmosphere of carbon dioxide in the greenhouse effect, his temperature is extremely high, up to a maximum of 4.8 even more degrees Celsius, aircraft cannot landed in the above, but he is very much like earth initial state, is very good study materials. Mars, earth and can be "sister planet", because the planet, or because sandstorm of iron, he's surface is red, this small planet to show the different side with Venus, dust storms, drought, and perhaps a human and tens of thousands of years. Jupiter, this planet, such as wood of the solar system's brother, his biggest characteristic is to see the great red spot, tornadoes, and that is the storm, it is the power of our big typhoon on thousands of times. Saturn and Neptune, first, Uranus, we known after a planet, I'm afraid you can't imagine how he turn, you dare to turn the circle go a little, though, but dare you forever are rolling walking, Uranus is outstanding. As a famous Neptune, he, he is not observed, but calculate out of 19th century, astronomers have discovered some rules of operation Uranus, they suspect a planet in "time", continuously, people finally got this planet Neptune. As to Pluto, in 2006 the international astronomical joint conference has revoked the planet Pluto, became a dwarf planet, nonetheless, for his desire to explore, even more than other planets.汉语翻译：我们的宇宙，神秘莫测，在我们的太阳系中，其所研究的价值，不亚于宇宙。
现在，让我们来看看，太阳系的成员。水星，一个徒有其名的星球，一滴水也没有，甚至于它的表面温差相当大，你若在那放一头猪，白天是烤乳猪，晚上就是冷冻猪肉。
金星，与水星恰恰相反，其极其浓厚的二氧化碳大气层使得在温室效应下，他的温度极其高，最高达到480多摄氏度，甚至于连飞行器都不能着陆在上面，不过他的现在很像地球初期的状态，是很好的研究材料。火星，可以和地球称得上是“姊妹星球”的行星，其由于沙尘暴，或又因为铁的原因，他的表面是红色的，这颗不起眼的星球去展现了与金星不同的一面，沙暴，干旱，或许展现的是人类及几万年后的世界。
木星，这颗类木行星，充当了太阳系的老大哥，他最大的特点就是龙卷风，看到那个大红斑了吗，那是个风暴，它比我们台风的威力要大上上千倍。土星，天王星，海王星，前一个我们众所皆知，后一个行星，恐怕你无法想象他是怎么转的，你敢转着圈走吗，虽然有点晕，但你敢一辈子都滚着走路吗，天王星就是这样的佼佼者。
至于海王星，他出名的一点，就是他不是观测到的，而是算出来的，19世纪，天文学家发现天王星的运行有些不规律，他们怀疑有一个行星在“作怪”，在不断的测算中，人们终于得到了这颗行星，海王星。至于冥王星，在2006年国际天文联合大会上，吊销了冥王星行星的资格，成了矮行星，尽管如此，人们对于他的探索欲望，甚至超过其他行星。
5. 用英文介绍八大行星
Jupiter Jupiter (5.2 AU), at 318 Earth masses, masses 2.5 times all the other planets put together. It is composed largely of hydrogen and helium. Jupiter's strong internal heat creates a number of semi-permanent features in its atmosphere, such as cloud bands and the Great Red Spot. Jupiter has sixty-three known satellites. The four largest, Ganymede, Callisto, Io, and Europa, show similarities to the terrestrial planets, such as volcanism and internal heating.Ganymede, the largest satellite in the Solar System, is larger than Mercury. Saturn Saturn (9.5 AU), famous for its extensive ring system, has similarities to Jupiter, such as its atmospheric composition. Saturn is far less massive, being only 95 Earth masses. Saturn has sixty known satellites (and 3 unconfirmed); two of which, Titan and Enceladus, show signs of geological activity, though they are largely made of ice.Titan is larger than Mercury and the only satellite in the Solar System with a substantial atmosphere. Uranus Uranus (19.6 AU), at 14 Earth masses, is the lightest of the outer planets. Uniquely among the planets, it orbits the Sun on its side; its axial tilt is over ninety degrees to the ecliptic. It has a much colder core than the other gas giants, and radiates very little heat into space.Uranus has twenty-seven known satellites, the largest ones being Titania, Oberon, Umbriel, Ariel and Miranda. Mercury Mercury (0.4 AU) is the closest planet to the Sun and the smallest planet (0.055 Earth masses). Mercury has no natural satellites, and its only known geological features besides impact craters are "wrinkle-ridges", probably produced by a period of contraction early in its history.Mercury's almost negligible atmosphere consists of atoms blasted off its surface by the solar wind.Its relatively large iron core and thin mantle have not yet been adequately explained. Hypotheses include that its outer layers were stripped off by a giant impact, and that it was prevented from fully accreting by the young Sun's energy. Venus Venus (0.7 AU) is close in size to Earth (0.815 Earth masses) and, like Earth, has a thick silicate mantle around an iron core, a substantial atmosphere and evidence of internal geological activity. However, it is much drier than Earth and its atmosphere is ninety times as dense. Venus has no natural satellites. It is the hottest planet, with surface temperatures over 400 °C, most likely due to the amount of greenhouse gases in the atmosphere.No definitive evidence of current geological activity has been detected on Venus, but it has no magnetic field that would prevent depletion of its substantial atmosphere, which suggests that its atmosphere is regularly replenished by volcanic eruptions.Earth Earth (1 AU) is the largest and densest of the inner planets, the only one known to have current geological activity, and the only planet known to have life. Its liquid hydrosphere is unique among the terrestrial planets, and it is also the only planet where plate tectonics has been observed. Earth's atmosphere is radically different from those of the other planets, having been altered by the presence of life to contain 21% free oxygen.It has one satellite, the Moon, the only large satellite of a terrestrial planet in the Solar System. Mars Mars (1.5 AU) is smaller than Earth and Venus (0.107 Earth masses). It possesses a tenuous atmosphere of mostly carbon dioxide. Its surface, peppered with vast volcanoes such as Olympus Mons and rift valleys such as Valles Marineris, shows geological activity that may have persisted until very recently.Mars has two tiny natural satellites (Deimos and Phobos) thought to be captured asteroids.Neptune Neptune (30 AU), though slightly smaller than Uranus, is more massive (equivalent to 17 Earths) and therefore denser. It radiates more internal heat, but not as much as Jupiter or Saturn.Neptune has thirteen known satellites. The largest, Triton, is geologically active, with geysers of liquid nitrogen.Triton is the only large satellite with a retrograde orbit. Neptune is accompanied in its orbit by a number of minor planets in a 1:1 resonance with it, termed Neptune Trojans.。
