Can the moon and stars appear in the night sky at the same time?

What can appear at the same time is just that sometimes we can't see it.

We can't see the following:

1, cloudy, especially when the clouds are thick.

2. In cities, on the one hand, air pollution reduces the visibility of urban air; On the other hand, the city's luminous pollution (also called city light at night) makes the night sky background too bright.

At the beginning and end of the lunar month, because the moon phase is a new moon at this time, its bright side is almost not facing away from the earth.

At the full moon, because the moon is too bright and the sky background is too bright, dim stars are hard to see. That's what "moon stars are rare" means.

Of course, the above 2 and 4 are similar, just like we can't see the moon and stars during the day. The key is that the sky is too bright to cover up their faint starlight.
