太阳系中的八大行星 Eight major planets in the solar system,目录,木星金星地球火星木星土星天王星海王星总结,水星 Mercury,水星介绍：Mercury introduced:水星距太阳五千八百万公里，是太阳系中和太阳最近的行星。水星没有卫星，它的体积在太阳系中列倒数第二位，仅比冥王星大。因为水星与太阳非常接近，所以它的白昼地表温度可高达摄氏四百二十七度；而到晚上又骤降至摄氏零下一百七十三度。Mercury 58 million kilometers from the sun is the solar system planets and the sun.Mercury is not satellite,it is the size of our solar system listed in the penultimate position,only Pluto large.Because Mercury is very close to the Sun,its surface temperature can be as high as the daytime temperature of 427 degrees;and also a sharp fall in the evening to minus 173 degrees Celsius 返回目录 Return to directory,金星 Golden Star,:金星介绍：Venus Introduction:金星，中国古代称之为太白或太白金星。它有时是晨星，黎明前出现在东方天空，被称为“启明”；有时是昏星，黄昏后出现在西方天空，被称为“长庚”。金星是全天中除太阳和月亮外最亮的星，犹如一颗耀眼的钻石，于是古希腊人称它为阿佛洛狄忒-爱与美的女神，而罗马人则称它为维纳斯-美神。天文上金星符号，即美神梳装打扮时用的宝镜。Venus,the ancient Chinese called Taibai or太白金星.It is sometimes Morningstar,there pre-dawn sky in the east,known as the Venus;sometimes evening,after dusk in the western sky,is called Venus.Venus is the day in addition to the sun and the moon outside the brightest stars,like a dazzling diamond,so the ancient Greeks called it Aphrodite-goddess of love and beauty,while others call it the Victoria Rome nass-United States and God.Astronomical symbols on Venus,that is,loaded up the United States when God Salisbury Hokyo used.返回目录 Return to directory,地球介绍：Earth Introduction:太阳系八大行星之一，地球自西向东自转，同时又围绕太阳公转。地球自转与公转运动的结合使其产生了地球上的昼夜交替和四季变化(地球自转和公转的速度是不均匀的)。同时，由于受到太阳、月球、和附近行星的引力作用以及地球大气、海洋和地球内部物质的等各种因素的影响，地球自转轴在空间和地球本体内的方向都要产生变化。地球自转产生的惯性离心力使得球形的地球由两极向赤道逐渐膨胀，成为目前的略扁的旋转椭球体，极半径比赤道半径短约21千米。One of the solar system eight planets,Earths rotation from west to east,and at the same time around the sun.Earths rotation and revolution movements combined to produce an alternating day and night on earth and the seasons change(the Earths rotation and the speed of revolution is uneven).At the same time,due to the sun,moon,and the nearby planets and the gravitational effect of Earths atmosphere,oceans and the Earths interior and other material factors,the Earth and the Earth in space自转轴the body must change direction.Earths rotation makes the centrifugal force generated by the inertia of the Earths spherical poles to the equator by a gradual expansion of the current rotation of the slightly flat ellipsoid,the equatorial radius of more than a very short radius of about 21 km。返回目录 Return to directory,地球 Earth,火星 Mars,火星介绍：Mars description:因为它在夜空中看起来是血红色的,所以在西方，以罗马神话中的战神玛尔斯(或希腊神话对应的阿瑞斯)命名它。在古代中国，因为它荧荧如火，故称“荧惑”。火星有两颗小型天然卫星:火卫一和火卫二(阿瑞斯儿子们的名字)。两颗卫星都很小而且形状奇特，可能是被引力捕获的小行星。英文里前缀-指的就是火星。In the night sky as it appears to be blood red,so in the West,to the Roman god of war Mars(or the corresponding Greek mythology,Ares)named it.In ancient China,because it is fiery Yingying,it referred to as the 荧惑.Mars has two small natural satellites:Phobos and Phobos 2(the names of the sons of Ares).Two satellites are very small and peculiar shape,may be captured asteroids gravity.English prefix-refers to Mars.返回目录 Return to directory,木星 Jupiter,木星介绍：Jupiter Introduction:木星是太阳系九大行星中最大的一颗，按离太阳由近到远的次序，它排第五。木星是夜空中最亮的几颗星之一，仅次于金星，通常比火星亮（除火星冲日时以外），有时比最亮的恒星天狼星还亮。中国古代称木星为岁星，并用它来纪年。当时人们认识到木星约十二年运行一周天，便把周天分为十二分，称为十二次，木星每年行经一次，就用木星所在星次来纪年，这种纪年法被称为岁星纪年法。木星的赤道半径为71400公里，为地球的11.2倍；体积超过地球的1500多倍；质量是地球的318倍，是太阳系所有其他行星总质量的两倍半。如此庞大的木星平均密度却相当低，只有1.33克/立方厘米。Jupiter is the largest of the nine planets of the solar system 1,according to from the sun is far from near to the order,it ranked fifth.Jupiter is the brightest night sky,one of several stars,second only to Venus,Mars than light(in addition to Mars day than red),sometimes more than the brightest star Sirius is also bright.Jupiter said in ancient China for岁星and use it to tomorrow.It is recognized that Jupiter was about twelve years running days a week,then divided into十二分Zhou,known as the twelve,Jupiter passing through the first year,where the stars used Jupiter to Jinian times,this method is called the age of Jinian Star Jinian law.Jupiters equatorial radius of 71,400 kilometers,11.2 times for the Earth;the volume of more than 1500 times the Earth;quality is 318 times the Earth,all the other planets in our Solar Systems two and a half times the total mass.Such a large average density of Jupiter is very low,only 1.33 grams/cubic centimeter.返回目录 Return to directory,土星 Saturn,土星介绍：Saturn introduced:土星是离太阳第六远的一颗美丽的行星，凡是用望远镜看过土星的人，无不惊叹不已。土星公转轨道半径为14亿千米，冲日时最大亮度为0.4星等。土星那橘色的表面，漂浮着明暗相间的彩云，配以赤道面上那发出柔和光辉的光环，远远望去真像个戴着顶大沿遮阳帽的女郎。要比两极半径大6000多千米。土星公转周期为29.5年，约合二十八宿之数，每年镇一宿，故古时我国又称其为“镇星”。土星长期被当作太阳系的边界，直到1781年发现天王星以后，太阳系才得以扩大。土星运动迟缓，人们便将它看作时间和命运之神的象征。罗马神话中称其为萨图努斯神，即希腊神话中的克洛诺斯，他是神王宙斯之父，是在推翻父亲之后登上天神宝座的。无论东方还是西方，都把土星与农业联系在一起。在天文学中的符号，像是一把主宰农业的大镰刀。Saturn is the sixth from the sun of a beautiful distant planet,seen with a telescope Saturn all the people,are amazed.Orbital radius of Saturns revolution of 14 million meters,the red on maximum brightness of 0.4 magnitude.That the surface of Saturns orange,white light floating clouds,with the equatorial plane and that the issue of soft halo of a bright,well looked really great along like a sun hat,wearing a top of the girl.Radius than the polarization of more than 6000 km.Saturns revolution period is 29.5 years,the二十八宿about a year the town one night,so in ancient times in China,also known as the town of Star.Saturn has long been regarded as the borders of the solar system,Uranus discovered until after 1781,was able to expand the solar system.Saturn,the slow movement,people will see it as time and a symbol of the god of fate.Roman Satu Yunus called God,that is,in Greek mythology克洛诺斯,he is God the father of King Zeus,after the overthrow of his father on the throne of God.Whether the East or West,all linked to Saturn and agriculture.The symbols in astronomy,such as a scythe is the key to agriculture.返回目录 Return to directory,天王星 Uranus,天王星介绍：Uranus introduced:天王星在太阳系中的位置排行第七，距太阳约29亿千米。它的体积很大，是地球的65倍，仅次于木星和土星，在太阳系位居第三；它的直径为5万多千米，是地球的4倍，质量约为地球的14.5倍。在古老的希腊神话中，天王星被看作是第一位统治整个宇宙的天神-乌拉诺斯。他与地母该亚结合，生下了后来的天神。是他费尽心机将混沌的宇宙规划得和谐有序。他地位显赫，译成中文便是天王星。Uranus in the solar system ranks the seventh position from the sun about 29 million meters.Its great size is 65 times the Earth,second only to Jupiter and Saturn,the third largest in the solar system;its diameter of more than 50,000 km,is 4 times the Earth,a mass of about 14.5 times the Earth.In ancient Greek mythology,Uranus is considered the first rule of the universe-the god Uranus.His mother and to the sub-binding,later gave birth to the gods.He tried to chaos in an orderly and harmonious universe planned.His prominent status,Uranus is translated into Chinese.返回目录 Return to directory,海王星 Neptune,海王星介绍：Neptune introduced:海王星是环绕太阳运行的第八颗行星，也是太阳系中第四大天体（直径上）。海王星在直径上小于天王星，但质量比它大。海王星是太阳系中最远的气体巨行星。它的赤道直径是49,500公里。如果海王星是中空的，它能够容纳将近60个地球。海王星上的一年相当于地球上的165年。它有8颗卫星，其中的6颗是被旅行者号发现的。海王星上的一天长16小时6.7分钟。Neptune is the eighth of the sun around the planet,but also the fourth largest in the solar system objects(diameter).Less than the diameter of Neptune in Uranus,but its large mass ratio.Neptune is the farthest solar system gas giant planets.Its equatorial diameter is 49,500 km.If Neptune is hollow,it can accommodate nearly 60 Earth.Neptunes year is equivalent to 165 years on Earth.It has eight satellites,six of which were found in Voyager.Neptune on 16 hours a day 6.7 minutes long.返回目录 Return to directory,总结 Summary,总结：Summary:我这次通过ppt幻灯片，了解了太阳系的八大行星，这是让我开心的事情。I have ppt slides through to learn about the eight major planets of the solar system,This is what I am happy.,谢谢观赏,
