1、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 su

2、n.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 Celsiu

6、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 nig

16、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 peop
