这只是一个很粗略的模拟器，如果放大到真实尺度，那月球的花瓣型轨道起伏很微小，几乎看起来是围绕太阳旋转，其实太阳对于月球的引力比地球大了2.5倍，但月球仍然是围绕地球旋转的 This is just a rough simulator. If you zoom in to the real scale, the petal-shaped orbit of the moon is very small, and it almost seems to rotate around the sun. In fact, the gravity of the sun to the moon is 2.5 times greater than that of the earth, but the moon is still Orbiting around the earth
