小行星

Under the precondition of above analyses, this research compares the meteorite-stricken cases in planets and secondary planets of solar system, the "shielding" and "eroding" effect in aerosphere, the scale of small planets and movement rules, then briefly analyzes the basic reason of mass meteorite-stricken events occurred in earth history.

在上述分析的前提下，本研究从太阳系有关行星和卫星表面陨击现象对比，大气层的"遮蔽"和"侵蚀"作用，小行星的规模及运动规律等方面简要分析了地球历史上大规模陨击事件发生的基本原因。

In the given dynamical models, all the possible dynamical factors which affect the movements of the NEAs are taken into account, including the gravitation of major planets and larger minor planets in the main belt area, the effects of the body flattening and the post-Newtonian influence from the sun's gravitation.

在给出的力学模型中，考虑了所有可能影响近地小行星运动的力学因素，包括各大天体和较大的主带小行星的引力作用、有关天体的扁率影响以及源于太阳引力的后牛顿效应。

Launched in 2007, the Dawn satellite is due to rendezvous with the large Vesta asteroids and with Ceres, the largest planetoid in the asteroid belt.

在2007年推出的&曙光&卫星目的是会合小行星灶神星和小行星带中最大的一员谷神星。

Space slugs are colossal, worm-like creatures that reside within the furrows and craters of asteroids and airless planetoids.

太空蛞蝓是巨大的，像虫一样的生物，居住在行星轨道间小行星或大气稀薄的小行星上的深沟或陨石坑中。

Moreover my thought the planetoid hits the Earth already is not the first time, the recent 300 years ago, everybody knew had diameter ten kilometers planetoids once to hit approximately to our Earth, the result in one piece panic, we passed through huge diligently to make several thousand super nuclear weapons and to launch successfully, finally gained the great decisive victory!

况且我认为小行星撞地球已并不是第一次了，最近的三百年前，大家都知道有一颗直径约十公里的小行星曾撞向我们地球，结果在一片恐慌中，我们经过一番巨大的努力制造了数千枚超级核武器并发射成功，最后取得伟大的决定性胜利！

This time, several main task personnel anxiously is waiting for the region senior official, as soon as saw the yellow senior official's to rush, immediately put through the event to report the place yellow race Mars interspace observation station, after Huang Qu senior official yellow Jinlong and the crew has greeted, directly arrived in front of the giant computer display monitor, not big a while, transmitted Mars aspect the live videotaping, saw only observes stationmaster a face startled appearance, saw the yellow senior official, immediately slightly calm, but still some aphasias explained religious doctrine:"Reports the yellow senior official, because in the short-term Milky Way nameless region will have a super giant star to have the violent detonation, instantaneous will produce in it the formidable shock-wave as well as will cause from this under the rapid change gravitational field together function, caused in the Milky Way correlation region to have a series of chain-reactions, finally forced a distance Earth probably is 20,000,000,000 kilometer diameter 100 kilometer about planetoids changed its original movement track; Latter passed through the home station most advanced computer to calculate repeatedly has obtained an astonishing result: This will change orbital the planetoid rapidly to hit after a year to ours Earth!"

此时，几名中心工作人员正急切地等待着区域长官，一见黄长官闯了进来，就立即接通了事件报告地点黄色人种火星星际观测站，黄区长官黄金龙与全体工作人员打过招呼后，就直接来到巨型电脑显示屏前，不大一会儿，就传来火星方面的实况录像，只见观测站长一脸惊慌的样子，见到黄长官，立刻稍微镇定了一下，但仍有些失语般地讲道：&报告黄长官，由于近期银河系无名区域内有一颗超级巨星发生猛烈的爆炸，在其瞬间产生的强大冲击波以及由此而导致的迅速改变的引力场共同作用下，引起银河系相关区域内发生了一系列的连锁反应，最终迫使一颗距地球大约为200亿公里的直径100千米左右的小行星改变了其原有的运行轨道；后又经本站最为先进的电脑反复计算得出了一个惊人的结果：这颗改变轨道的小行星将于一年后急速撞向我们的地球！&

For main-belt objects this can occur after the object has been observed on two or more nights at four oppositions (although this depends on the number and distribution of the observations as well as their quality); NEOs can receive a number after two or three well-observed oppositions.

对于主带小行星，只要在4个冲日内观测到两个或更多的夜晚（虽然这依赖观测的数量和分配以及观测的质量），就可以获得正式编号；对于近地小行星，只要获得两个或三个比较好的冲日数据，就可以获得正式编号。

Astronomers announced the discovery of a new planetoid in the Kuiper Belt, an asteroid belt located in the outer fringes of our solar system.

天文学家宣布，他们在太阳系外缘的小行星带&柯伊伯带&中发现了一颗新的小行星。

The Earth was made by the collision of billions of planetesimals, chunks of rock and ice much like today's asteroids and comets.

地球是由数十亿记的小行星碰撞所形成的，巨石和冰块更像是今天的小行星和彗星。

The Earth was made by the collision of billions of planetesimals, chunks of rock and ice much like today's asteroids and comets.

地球是由于亿万的小行星体、岩石块和冰块之间碰撞产生的，很象现在的小行星和彗星。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
