英语作文关于火星70词并翻译

Answer 1

火星是太阳系九大行星之一，按离太阳由近到远的顺序，火星排在地球的后面，列为第四。它的平均直径为6790公里，约为地球直径的一半。它的密度也比地球小，为3.933克/立方厘米（地球为5.52克/立方厘米）。火星与太阳的平均距离为228000000公里，环绕太阳一圈约相当于地球上的687天。火星上的一天相当于地球上的24小时37分22.6秒，比地球的一天稍长一点儿。火星有两个小卫星：火卫一和火卫二。火星的自转轴同地球一样，也是倾斜的，同时因为它也具有大气，所以也和地球一样有四季节变化。火星表面的平均大气温度为零下23摄氏度。火星没有可检测出的磁场，连同它密度小的情况，可以认定它没有大型的金属内核
