When does the forecast schedule of Leonid meteor shower usually appear?

For those who are interested in astronomy, it is particularly important to have a detailed timetable. Leonid meteor shower is the king of meteor shower, which is worth seeing. Therefore, knowing the schedule of Leonid meteor shower in advance is conducive to our better observation. Then let's use constellation knowledge to reveal the timetable of Leonid meteor shower.

Forecast schedule of Leonid meteor shower

When does the Leonid meteor shower usually appear? Leonid meteor shower appears around 165438+ 10/4 to 2 1 every year. The Leonid meteor shower, known as the king of meteor showers, is a meteor shower connected with Comet Templeton, with a period of about 33 years. Generally speaking, the number of meteors in the Leonid meteor shower is about 10 to 15 per hour, but the Leonid meteor shower peaks once every 33 to 34 years on average, and the number of meteors can exceed several thousand per hour. This phenomenon is closely related to the period of comet Temple-Tuttle.

Extended data:

The reason of Leonid meteor shower is 1. Meteors are usually sporadic and have nothing to do with each other. The time and direction of its occurrence are irregular. You can see about 10 meteors every hour on average. They are called accidental meteors (also called accidental meteors). Sometimes in a certain area of the sky, the number of meteors will increase obviously in a certain period of time, with dozens or more meteors per hour, which looks like rain. This phenomenon is called meteor shower. 2. A particularly large meteor shower is also called a meteor shower. Meteor shower is the result of a large number of meteoroids breaking into the earth's atmosphere. This group of meteoroids is called meteor group. 3. The famous Leonid meteor shower is not Leonid meteor shower. Even if Leo has a meteor shower, it can't be seen by the naked eye on the earth. Leonid meteor shower is formed by particles scattered in the atmosphere by a comet named Temple-tuttle. Because the projection of the formation direction of the meteor shower on the celestial sphere coincides with the projection of the Leonid meteor shower on the celestial sphere, it seems that the meteor shower is ejected from the earth's Leo, so it is called the "Leonid" meteor shower. It is generally believed that meteor shower is related to comets. Comet is a strange celestial body in the solar system. When they are far away from the sun, they will appear as cometary nuclei with a diameter of several kilometers or even larger. Once close to the sun, under the influence of solar radiation, due to the evaporation of comet nuclear material, huge tails and long tails will be formed. When a comet approaches the sun, it will melt ice into dust particles, most of which are larger than sand. For most comets near the earth, they will burn in the atmosphere and form meteorites. Meteor swarms originate from scattered material fragments or the disintegrated nuclei of comets. Small particles scattered by comets in orbit are unevenly distributed. Some places are sparse, while others are dense. When the earth meets a place where particles are very thin, there will be fewer meteors. When the earth meets a place with dense particles, there will be more meteors.
