What kind of weather can you see a meteor shower?

Only in a clear night sky with no clouds blocking the view can you see the meteor shower, but the appearance of the meteor shower is irregular.

There are a lot of meteoroid dust and solid blocks in the solar system. When these "space dust" break into the Earth's range, they will rub against the atmosphere and burn, becoming the meteors we see every day. The appearance of meteors is usually single and sporadic, and their appearance time and direction are irregular. Such meteors are called "sporadic meteors". Under good weather conditions, about 10 sporadic meteors can be seen per hour.

Many meteors scatter outward from a certain point in the starry sky (called a radiant point). In fact, the meteor groups are roughly parallel when flying towards the earth, and the radiant point is a visual perspective image. The cause of the meteor shower is that the earth encounters a dense group of meteoroids. The meteor group is formed by the material broken down by periodic comets or the disintegrated comet nucleus. Therefore, the meteor group and its parent comet have roughly the same orbit. Because the meteor group The orbits of these meteor groups are quite fixed, so the Earth will periodically pass through these meteor groups, forming a regular meteor shower.

Tips for watching meteor showers

1. Try to go to the wild, find a darker place, and observe in a fixed place for a long time

Most meteors are dark meteors , the darker the night sky, the easier it is to see, and it is easier to observe in the wild than in the city. Of course, this excludes sandstorms, dark clouds, and thunderstorms. If you are more patient and perseverant, it is recommended to observe a certain place for a long time. You can observe less than 10 meteors in an hour.

2. Try to observe from 0 a.m. to before sunrise

Due to the rotation and revolution of the earth, the number of meteors from 0 a.m. to before sunrise is generally higher than in the first half of the night. More, and less affected by the moon and lights in the second half of the night.
