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。在古代中國,因為它熒熒如火,故稱“熒惑”。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。 In the night sky as it appears to be blood red, so in the West, to the Ro
