Why can't you see the moon and stars in the sky on a rainy night?

The period of the moon's revolution around the earth is 1 month. In this month, if the moon turns to the side facing the sun, it means that the moon only rises during the day, which is difficult for us to see. But when the moon turns to the side facing away from the sun, we can see that the moon rises at night. Because the moon revolves around the earth, it rises at different times every day, and it gets later every day, so there will be times when the moon can't be seen at night. Tanabata is the seventh day of the lunar calendar. It's the first quarter moon. Shortly after sunset, the moon can still be seen in the western sky, but it sets in the middle of the night, so it can't be seen. If you saw it in the middle of the night and didn't see it, there are several possibilities. 1: The moon is already very low, and it is going to set. You didn't notice that direction. You didn't notice the bad weather that day.

The reason why you can only see the moon without stars at night is that although the moon is bright, it will weaken the surrounding starlight, but even in a big city, you can still see a few stars on a clear night, so the reason may be that the weather is bad that night, although it may be sunny, but if the air pollution is serious or there is some fog, the stars can't be seen, and only the bright moon can be seen.
