What is the reason behind?

According to Li Zhifei, a staff member of the Yunnan Observatory of the Chinese Academy of Sciences, from the astronomical point of view, when the earth is in the middle of the moon and the sun, the moon we see on the ground is the most round when the moon is in front of the earth; , The ground can't see the moon. Generally speaking, we call a cycle of the lack of the moon circle as a "Shuangwang Moon", which is called "Shuo Ri" that cannot be seen at all. ", Usually the fifteenth or sixteen of the lunar calendar.

The cycle of Shuangwangyue is about 29.5 days. That is, about 14.75 days, the moon will just turn to the rear of the earth. Li Zhifei said that the rotary track of the moon is not round but oval, and the moon's rotation track itself is also rotating. The gravity of the moon is different, making the moon's rotation speed uneven. Therefore, there is also a difference between the time when the moon appears behind the earth. Sometimes it may be a little faster. It may be the fifteen moon of the fifteen moon, and sometimes a little slower, that is, fifteen, sixteen circles, and even seventeen circles.
