怎么用matlab 做一个地球围绕太阳的模型地球是怎样围绕太阳转动的一颗行星,在太阳周围还有其它的行星吗?还有哪些星体围绕太阳转动? 哥白尼是怎样发现地球围绕太阳转动的为什么太阳要转动?太阳为什么要围绕地球转动地球每秒围绕太阳转动多少千米? 如果在剩下的50亿年里有个颗行星穿过宇宙来到银河系围绕太阳转动那个到时候地球会怎么样公转就是地球围绕着太阳转动.公转的方向是(),公转的周期是(). 昼夜交替时由于太阳东升西落围绕地球转动而形成的. 1.昼夜交替是由于太阳东升西落围绕地球转动而形成的. 科学家是根据( )证明了地球确实是围绕太阳转动的改病句：谁也不能否定地球不是围绕太阳转动的月亮围绕地球,地球围绕太阳近似做什么运动
