When will there be a meteor shower? Or some other astronomical wonder?

You just think of every star as a meteor shower.

Meteor showers are usually more likely to occur between 2:15 a.m. and 4:45 a.m.

A meteor shower is an astronomical phenomenon in which many meteors are emitted from a so-called radiant in the sky in the night sky. These meteors are fragments of the universe known as meteoroids, which are projected into the Earth's great hail layer at polar high speeds as they orbit in parallel orbits.

Features of the Meteor Shower Hall:

Most meteoroids are smaller than gravel, so almost all meteoroids are destroyed in the atmosphere and do not hit the Earth's surface; Debris that is capable of hitting the Earth's surface is called a meteorite.

Meteor showers that are particularly large or unusual in number are known as "meteor outbursts" or "meteor storms" and can produce more than 1,000 meteors per hour. Before sunrise on October 21-22, 2018, the Orionid meteor shower will reach its maximum.

There are a few things to note about meteor showers:

First of all, meteor showers are not like rain as expected, as long as the meteors come out of a radiant, they can be considered meteor showers. There are nearly 40 meteor showers that can be called meteor showers every year, and you only have to think about how many meteors you can see every year. The larger meteor showers each year include the Quadrant meteor shower around January 4, the Lyrid Lyrid meteor shower around April 22, the Perseid meteor shower on August 13-14, the Leonid meteor shower on November 17-18, and the Geminid meteor shower around December 14.

Second, it is difficult to predict meteor showers to the hour, because the mass of matter that forms meteor showers is very small, and the slightest gravitational disturbance will change the time to reach the Earth.

Again, you must not use a telescope for meteor showers, you can use the naked eye, and the use of telescopes will seriously affect the effect because of the small field of view received.

Finally, my advice is that if you're not a hobby of astronomy and just want to see meteor showers, don't look no further. In fact, this is largely the result of the fact that the reporter does not understand astronomy and hype. They thought the meteor showers were the same as the one in 2001.

In addition to having enough comet fragments, that is, meteoroids, to produce a meteor shower, it is also necessary for them to move along the orbit of the parent comet, and at the same time, there is an intersection point with the Earth's orbit, and the Earth and the meteoroid group move to the vicinity of the intersection at the same time, and the meteor shower phenomenon is prone to occur. Dust particles from outer space break into the Earth's atmosphere, rub against the atmosphere, and generate a lot of heat, which vaporizes the dust particles. Meteors are formed by emitting light in the process.

Dust particles are called meteoroids.

At certain times, a certain number of meteors can be seen as their reverse extensions all passing through a small celestial region. These are meteor showers.

Meteor showers are formed due to the fragmentation of celestial bodies such as comets. The reason why meteoroids leave celestial bodies such as parent comets is that comets are mainly composed of ice and dust.

As the parent body of these meteoroids moves closer to the Sun, the ice vaporizes, causing dust particles to be ejected out of the parent body and into the comet's orbit like fountain water. In summary, when these large amounts of debris gather and fly to the intersection point of the Earth's orbit, the meteor shower is produced.
