What is a meteor.
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.
Velocity. A tiny meteoroid is enough to produce a bright light that can be seen at a distance of nearly 100 kilometers, due to the high speed of the meteoroid.
The color of a shooting star.
The color of a meteor is a reflection of the chemical composition of the meteoroid and the temperature of the reaction: sodium atoms emit orange light, iron is yellow, magnesium is blue-green, calcium is purple, and silicon is red.
Sound. Meteors usually don't make audible sounds. If you don't see it, it will pass by silently.
For very bright meteors, it is possible to have heard a sound. These sounds are mainly concentrated in the low-frequency band. A very bright meteor, such as a fire meteor, may be audible.
Lasting aftermath. A meteor sometimes leaves a lasting trail in the orbit it passes. The color of the remnant body is mostly green, and it is a neutral oxygen atom.
The duration is usually 1 to 10 seconds. It can be seen that the brightness of the aftertrace decreases rapidly. These bright lights come from the hot air and metal atoms in meteoroids.
Meteor shower. 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.
Where do meteor showers come from.
Meteor showers are formed due to the fragmentation of celestial bodies such as comets.
Why does a meteoroid leave a celestial body such as a parent comet?
Comets are mostly made up 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.
So, at certain times, a certain number of meteors can be seen as the reverse extension lines all pass through a small celestial region. These are meteor showers.

Some space debris enters the Earth's atmosphere and burns against the atmosphere.

A meteor shower is a group of meteors that exhibit similar trajectories in time and space. They all come from the same comet, and when the Earth orbits the Sun around the comet's dust belt, it collides with the comet dust, causing a large number of meteors to streak across the night sky. Meteor shower is a beautiful and magical phenomenon, which streaks through the night sky and brings people infinite reverie and beautiful imagination.
So, how did meteor showers form in Nayin? Here are some explanations of how meteor showers are formed:
When the Earth orbits the Sun around the comet's dust belt, it collides with comet dust. Due to the high speed of comet dust, when they enter the Earth's atmosphere, the resistance of air friction causes high temperatures, causing the comet dust to oxidize rapidly, releasing huge amounts of energy, emitting light and burning into meteors. Because comet dust is so fast, meteors usually burn up and disappear into the night sky within a few seconds.
Meteor shower viewing usually requires choosing an appropriate time and place for observation. Because the density and number of meteor showers vary, it is important to observe them on a clear night in a place where there is no light pollution. In addition, it is best to choose an open place when observing and avoid the obstruction of objects such as tall buildings.
In conclusion, the meteor rain is formed by the burning of meteoroids in the Earth's atmosphere in the comet dust belt, and it is a very spectacular and magical natural phenomenon. We can enjoy this beautiful sight at the right time and place, and feel the magic and beauty of nature.
Each meteor shower is active at a specific time of the year. For example, the Perseid meteor shower is at its peak on August 12 every year, which is my birthday. So every year on my birthday, I will pay attention to the weather forecast, is it on the mountain? Or is it to celebrate at home? >>>More
Meteor showers are astronomical phenomena.
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 that are projected into the Earth's atmosphere at extremely high speeds as they orbit in parallel orbits. 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. >>>More
December is destined to be a romantic month. In addition to the total lunar eclipse, on the 14th of this month, the starry sky will also be romantic, and the Geminids, Ursid meteor showers, and Mercury's western elongation are also worth looking forward to. >>>More
There are peach and plum drunk spring breeze search network.
It's true. At the shutdown ceremony, producer Yao Jia said that the next recent plan is to shoot a SP movie theater version of "Meteor Shower", relying on the strong audience accumulated by "Meteor Shower" to enter the film industry. You must know that the SP theatrical version of the movie is not a new model in Japan and South Korea, popular animations and idol dramas generally shoot this kind of special edition movie, and Hunan Satellite TV is about to shoot the movie version of "Meteor Shower", which will also refresh the model of its self-made drama again, and continue to move closer to the international advanced level. >>>More
