How is the meteor shower formed?

The formation of meteor shower is that the meteors in the sky are broken for some reason. Under the force of outer space, these scattered fragments swept the earth and produced the meteors we saw. When the number of broken stars is huge, meteor showers are produced.

Meteor shower is a phenomenon that meteors in the sky are broken for some reason. Meteors are small celestial bodies (such as comets or asteroids) in space. When they are close to the sun, they will be affected by solar radiation, causing the ice and rocks on their surfaces to evaporate. The gas and particles produced by evaporation form bright tails, making meteors visible in the atmosphere.

The formation of meteor shower needs a specific condition, that is, the earth passes through the orbit of a comet or an asteroid, so that the earth meets these debris. Under the gravity of outer space, these scattered fragments swept across the earth, rubbed with the earth's atmosphere to generate friction heat and burned into bright light tracks. Due to the huge amount of debris, there has been a continuous meteor phenomenon, forming a meteor shower.

The names of meteor showers are usually related to the constellations they pass through, such as Leonid meteor shower and Mid-Autumn meteor shower. Meteor showers are usually active within a specific time window. People will observe and predict the time and intensity of meteor shower in advance, and choose a suitable observation site in order to better appreciate this spectacular sky phenomenon.

Meteor shower characteristics:

1, Ornamental: The meteor shower is a beautiful astronomical performance, attracting many viewers. In the clear night sky, the audience can see many twinkling meteors streaking across the sky, forming a series of bright lights, giving people a shock and aesthetic feeling.

2. Periodicity: The meteor shower has a certain periodicity, and the same meteor shower activity occurs every year. Some famous meteor showers, such as constellation meteor shower and Orion meteor shower, have a fixed activity time every year, so people can know and plan to watch them in advance.

3. Atmospheric combustion: Meteor shower is caused by the friction between the debris of asteroids or comets orbiting the earth and the atmosphere. When these fragments enter the earth's atmosphere, air molecules will be excited and ionized due to high-speed motion and frictional heat, resulting in a short-lived bright fireball.

4, be vividly portrayed: Meteor shower observation usually requires clear weather, cloudless Wan Li, and far away from urban light pollution, in order to enjoy the best. People can choose appropriate observation points, such as suburbs, mountains or observatories, to improve the observation effect.

5. Abrupt and short: Meteors in a meteor shower will quickly cross the night sky, and the appearance and disappearance of meteors are often abrupt and the duration is relatively short. Therefore, the audience needs to stay focused and actively look for it in order to catch the meteor.
