【正文】 系八大行星之一，地球自西向東自轉(zhuǎn)，同時又圍繞太陽公轉(zhuǎn)。地球自轉(zhuǎn)與公轉(zhuǎn)運動的結(jié)合使其產(chǎn)生了地球上的晝夜交替和四季變化 (地球自轉(zhuǎn)和公轉(zhuǎn)的速度是不均勻的 )。同時，由于受到太陽、月球、和附近行星的引力作用以及地球大氣、海洋和地球內(nèi)部物質(zhì)的等各種因素的影響，地球自轉(zhuǎn)軸在空間和地球本體內(nèi)的方向都要產(chǎn)生變化。地球自轉(zhuǎn)產(chǎn)生的慣性離心力使得球形的地球由兩極向赤道逐漸膨脹，成為目前的略扁的旋轉(zhuǎn)橢球體，極半徑比赤道半徑短約 21千米。 One of the solar system eight plas, Earth‘s rotation from west to east, and at the same time around the sun. Earth’s rotation and revolution movements bined to produce an alternating day and night on earth and the seasons change (the Earth‘s rotation and the speed of revolution is uneven).At the same time, due to the sun, moon, and the nearby plas and the gravitational effect of Earth’s atmosphere, oceans and the Earth‘s interior and other material factors, the Earth and the Earth in space自轉(zhuǎn)軸 the body must change direction. Earth’s rotation makes the centrifugal force generated by the inertia of the Earth‘s 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。 返回目錄 Return to directory 地球 Earth 火星 Mars 火星介紹： Mars description: 因為它在夜空中看起來是血紅色的 ,所以在西方，以羅馬神話中的戰(zhàn)神瑪爾斯 (或希臘神話對應(yīng)的阿瑞斯 )命名它。在古代中國，因為它熒熒如火，故稱“熒惑”。火星有兩顆小型天然衛(wèi)星 :火衛(wèi)一和火衛(wèi)二 (阿瑞斯兒子們的名字 )。兩顆衛(wèi)星都很小而且形狀奇特，可能是被引力捕獲的小行星。英文里前綴 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 熒惑 . Mars has two small natural satellites: Phobos and Phobos 2 (the names of the sons of Ares
