The moon is different from the earth in many respects. First of all, there is no known life on the moon. And in terms of size, it is much smaller than the earth. You may think both of them have the same spherical shape. But strictly speaking, they are not the same. The moon is almost a perfect sphere; its diameter differs by no more than 1% in any direction. The faster an astronomical object spins, the more it becomes bulged at the equator and flattened at the poles. ________________________________

So spinning objects undergo some changes of their shape, except for the moon and the earth.

Since the moon rotates more slowly than the earth, it is more nearly spherical.

Moreover, the moon’s diameter has been varied for the last hundred years.

In fact, the moon’s spherical shape is rather unexpected, considering its density and gravity.
