金星是太阳系中八大行星之一，按离太 阳由近及远的次序是第二颗。它是离地 球最近的行星。中国古代称之为长庚、 启明、太白或太白金星。公转周期是 224.71地球日。夜空中亮度仅次于月球 ，排第二，金星要在日出稍前或者日落 稍后才能达到亮度最大。它有时黎明前 出现在东方天空，被称为“启明”；有时 黄昏后出现在西方天空，被称为“长庚” 。Venus is that the solar system is hit by one of eight major planets, according to being away from the sun from the close-by examples to those far off order is second. It is a planet from when the earth is nearest. China was called in the ancient times ancient Chinese name for Venus , open Ming Dynasty , Tai Bai or very white Venus. The period of revolution is 224.71 earth days. Brightness is next only to the moon , arranges second in the night sky, Venus needs to go forward slightly in sunrise possibly sunset queen ability reaches the brightness maximum slightly. It appears in front of dawn in the east sky sometimes , the quilt is called “opening Ming Dynasty “; Be sometimes appeared in the west sky , be called after the dusk “ancient Chinese name for Venus“. 水星 ，中国古代称为辰星。是太阳系中 的类地行星，也是岩态行星，其主要由 石质和铁质构成，密度较高。自转周期 很长为58.65天，自转方向和公转方向相 同，水星在88个地球日里就能绕太阳一 周，平均速度47.89km/s，是太阳系中运 动最快的行星。无卫星环绕。它是八大 行星中是最小的行星，也是离太阳最近 的行星。Mercury China was called the time star in the ancient times. Be terrestrial planet in the solar system , be also a rock state planet, the person is taller than mainly comparatively from stone with irony formation , density. The rotation period is 58.65 day very often, rotation direction and revolution that direction is identical , Mercury is therefore likely to wind sun circle , 47.89 km/s sharing speed within 88 earth days, is to move the quickest planet in the solar system. Be encircled by nothing artificial satellite. That it is eight is a minimal planet in the major planet , is also a planet from when the sun is nearest. 地球是太阳系从内到外的第三颗行星 ，也是太阳系中直径、质量和密度最 大的类地行星。赤道半径为6378.2公 里，其大小在行星中排列第五位。地 球有大气层和磁场，表面的71%被水 覆盖，其余部分是陆地，是一个蓝色 星球。地球是包括人类在内上百万种 生物的家园，也是目前人类所知宇宙 中唯一存在生命的天体。地球已有45 亿岁，有一颗天然卫星月球围绕着地 球以27.32天的周期旋转，而地球自西 向东旋转，以近24小时的周期自转并 且以一年的周期绕太阳公转。The earth is that the solar system is also that the solar system is hit by the diameter , mass and maximal terrestrial planet of density from inner to external third planets. The equator radius is 6378.2 kilometres , its size arranges fifth places in the planet. The earth has atmospheric layer and the magnetic field , that 71% quilt water of surface covers , other parts is terrestrial, is a blue celestial body. The earth is including inclusive human being home of up to million kind living things , is also that what human being knows universe middle is at present unique existence the life celestial body. The earth already has had 4,500,000,000-year-old , the period having a natural artificial satellite moon to use 27.32 day about the earth rotates , self the earth west faces but east revolution , 24 hours of period rotation and the period with 1 year go round the sun up to revolution. 火星是太阳系八大行星之一，是太阳 系由内往外数的第四颗行星，属于类 地行星，直径约为地球的一半，自转 轴倾角、自转周期均与地球相近，公 转一周约为地球公转时间的两倍。在 西方称为“战神玛尔斯”，中国则称为 “荧惑”。橘红色外表是因为地表的赤 铁矿（氧化铁）。火星基本上是沙漠 行星，地表沙丘、砾石遍布，没有稳 定的液态水体。二氧化碳为主的大气 既稀薄又寒冷，沙尘悬浮其中，每年 常有尘暴发生。火星两极皆有水冰与 干冰组成的极冠，会随着季节消长。That Mars is the solar system one of eight major planets, is that the solar system belongs to a terrestrial planet from fourth planets that the inner counts to the outside, the diameter makes an appointment with being terrestrial halves, the axis of rotation dip angle , the rotation period without exception are close to the earth, revolution a circle is double times of revolution of the earth time about. Be called “Mars Maersi “ in the west, China is to be called “Mars “. Red outward appearance of tangerine is the haematite because of the earths surface (iron oxide). Mars is that the desert planet , the earths surface sand dune , gravel are found everywhere mainly , does not have the stable liquid state wave. Carbon dioxide give first place to atmosphere is both thin and chill, fine sand flying up in the air suspension is among them , Chang has a dust devil to happen every year. Mars two poles all extreme crown having water ice and dry ice composition , will be with season growth and decline. 木星，为太阳系八大行星之一，距太阳 （由近及远）顺序为第五，亦为太阳系 体积最大、自转最快的行星。木星已知 63颗卫星，木星主要由氢和氦组成，中 心温度估计高达30,500。古代中国称 之岁星，取其绕行天球一周为12年，与 地支相同之故。西方语言一般称之朱比 特（拉丁语：Jupiter），源自罗马神话 中的众神之王、相当于希腊神话中的宙 斯。Jupiter, is the solar system one of eight major planets, from when the sun (from the close-by examples to those far off) is fifth in proper order, also for the solar system volume maximum , the quickest planet of rotation. Jupiter already has known 63 artificial satellites , Jupiter is composed of hydrogen and helium mainly , centre temperature estimation height amounts to 30,500 C. Ancient China calls that Jupiter , fetch its passing round celestial sphere circle being 12, reason of being same as the terrestrial branch. The west calls that vermilion bit (Latin like language: King , Zeus in being equal to Greek mythology of Jupiter)
