What is a meteor shower and what is the phenomenon of a meteor shower

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.

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.

Radiant of meteor showers: Meteor showers appear to be emitted from the same point in the sky, which is called a radiant. Actually, it's because of perspective.

All meteoroids move in parallel directions during a meteor shower, but just as we stand on a railroad and look at two railroad tracks converging at one point, it looks as if these meteoroids are coming from a single point and going in all directions. Conversely, to determine whether a meteor is part of the meteor group, you only need to see that its reverse extension does not pass the radiant.

Meteor shower maximums and bursts: All meteor showers are not visible only at a certain moment, but are often observed for several days or even a month. But most of the time the flow is very small, and only in a relatively small period of time will a large number of meteor showers appear, at this time we call the meteor shower maximum; The eruption is mainly for some periodic meteor showers, and in most years, even if the flow is very small, there is a possibility of a particularly high flow in some years, which is the explosion.

A meteor shower is a phenomenon in which a swarm of meteors burns and is formed as a result of the breakup of a comet.

The principle of meteor shower formation.

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, it is not a celestial body. When a meteoroid meets the Earth, due to the influence of gravity, it rubs against the atmosphere and glows when it falls into the Earth.

It becomes a magnificent meteor shower.

Solar system. In addition to the sun and the eight planets.

and its moons, asteroids, comets, in interstellar space.

There are also large quantities of dust particles and tiny solid masses that also orbit the Sun, collectively known as "meteoroids".

Introduction

The mass of meteoroids is generally less than 100 tons, and most meteoroids are just small solid particles. Some meteoroids revolve around the Sun in groups along similar orbits, but the perihelion is in different sequences, and they form "meteoroids (groups)"; Some meteoroids are like stragglers, orbiting the sun individually.

When a meteoroid passes through the Earth's attachment during orbit, it will be affected by the Earth's gravity and will break into the Earth's atmosphere at high speed, rubbing against the atmosphere and converting kinetic energy into heat energy. It makes meteoroids ablate and glow, and some become bright fire meteors.
