Did anyone see a meteor? What does it mean to see a shooting star?

To answer this question, it is perfectly possible to excerpt the meteor shower activity table, excerpt the meteor shower activity in July, and explain a few terms by the way. In this way, it must be professional, comprehensive, descriptive, and clear, and there is no pressure to win the best.

But the question is, can this help the landlord? The answer is no. A few questions are enough to show that the landlord has never seen a meteor shower and asked many specious questions.

To get back to the point, the International Meteor Organization mandates 31 major meteor showers, with about 10 events in July. But I don't want to list their names and traffic one by one, because the vast majority of meteor showers, even if they have the title of "main", are still four words, not worth mentioning.

Fortunately, there is an exception to this meteor shower in July, that is, the Southern Aquariids δ meteor shower, which is at its peak on July 28, and the meteor shower in July can be said to stand out from the crowd, with a flow of about 20; Consider the airport's sister meteor shower at a similar time and radiant, and the total flow can reach 30-40. However, compared with the year-round meteor shower, it can only be said that Liao Hua is the pioneer.

From a personal point of view, if the purpose is to watch the excitement, this meteor shower is not too worthy of attention. The first is the mediocre flow, which determines that this meteor shower can only be relegated to the second rate; Moreover, because of this year's moon phase, although the moonlight is clear and bright, it is also the enemy of astronomical observation. The relatively objective statement is that "the moon and stars are rare", and the poetic one is "the river and the sky are free of fiber dust, and the lonely moon wheel in the bright sky".

Make a mathematical estimate to the landlord, if you come to the suburbs, the limit magnitude can only be equal to about (barely see the Milky Way) under the moonlight, and the number of meteors that can be seen from 11 o'clock to 4 o'clock the next day is about: 5 (observation time) * 30 (flow) * moonlight interference) * radiant height) = one, I don't know if this value is satisfied? If you are in the city, please also give a 3% discount on the original basis.

Below is a photograph of a Leonid meteor, which can be said to be quite shocking. Do you find any of the characteristics? The reverse extension of all meteor trajectories passes through a point called the radiant.

The constellation in which the radiant is located is called the XX meteor shower. As long as a number of meteors meet these properties, it can be called a meteor shower, and even if there are only a few meteors in one night, there is no correlation between the meteor shower and the number.

There may or may not be because he froze to death.

From a scientific point of view, it indicates a high level of atmospheric activity. However, for meteors, some people say that a meteorite will disappear, and some people even say that there is less garbage in the universe.

Meteors usually appear sporadically and have nothing to do with each other, and the timing and direction of their appearance are irregular, with an average of about 10 meteors per hour. Meteoroids originally moved around the Sun, and when they passed near the Earth, they were affected by the Earth's gravitational pull and changed their orbit and entered the Earth's atmosphere. There are several types of meteors: single meteors, fire meteors, and meteor showers.

Most of them are burned to ashes before they fall to the ground, and a few will fall to the ground as meteorites.

Meteor is a meteorite collides with the earth's atmosphere after sparks and then falls on the earth, according to science, like a meteor wish will not be fulfilled at all, but in the legend, it is the meteor as a sacred thing, to make a wish to him, people have always believed that the purpose can be achieved, not so much to make a wish, but to say that people yearn for it at that time.

Legend has it that a meteor represents the fate of a person, and a falling meteor is actually the tears shed by angels. If you can capture the moment when a meteor crosses the sky and make a beautiful wish, then God will help you make it happen.

Meteors are formed by sparks from space objects entering the Earth's atmosphere!

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.

Meteors are traces of light produced by the friction and combustion of dust particles and solid blocks (meteoroids) in interplanetary space into the Earth's atmosphere. If they are not burned up in the atmosphere, they are called "meteorites" or "meteorites" when they fall to the ground. Meteoroids originally orbited the sun, and when they passed near the earth, they were affected by the gravitational pull of the earth and changed their orbit, thus entering the earth's atmosphere.

There are several types of meteors: single meteors, fire meteors, and meteor showers. There is no law on the time and direction of the appearance of a single meteor, which is also called an occasional meteor. Fire meteors are also occasional meteors, but they are very bright when they appear, like a fire dragon and may be accompanied by ** sounds, and some are even visible during the day.

Many meteors radiate outward from a certain point in the starry sky (radiant), which is called a meteor shower. Meteorites are the remnants of the largest meteoroids in the solar system that have not completely burned up after breaking into the Earth's atmosphere, and they bring us a wealth of information about the formation and evolution of the celestial bodies in the solar system, and they are welcome guests. The density of ordinary meteoroids is very low, about 1 20 of the density of water.

Every day, billions or tens of billions of meteoroids enter the Earth's atmosphere, and their total mass can reach 20 tons.

Take whatever you want!

It's good to be happy!

Natural phenomenon.

Meteors1 are small objects and dust particles distributed in interstellar space, called meteoroids. They fly into the Earth's atmosphere and rub heat and light against the atmosphere, a phenomenon called meteors. Meteors are commonly referred to as meteoroids that emit light for a short period of time. Commonly known as the thief star.

Meteor 2 [liúxīng] An ancient weapon with a hammer tied to each end of an iron chain. A type of acrobatics in which a bowl or fireball containing water is tied to the ends of a long rope and the rope is swung by hand to make the bowl or fireball fly in the air.

Explanation: Meteors.

In addition to the sun, the eight planets and their moons, asteroids, and comets, there are also a large number of dust particles and tiny solid masses in interplanetary space, which also move around the sun. When approaching the Earth, the Earth's orbit is altered by the gravitational pull of the Earth, making it possible to pass through the Earth's atmosphere. Alternatively, it is possible to enter the Earth's atmosphere as the Earth passes through their orbit.

Due to the high speed of these particles relative to the earth (11 72 km/s), they burn and emit light by violent friction with atmospheric molecules, and appear as a trail of light in the night sky, a phenomenon called meteors, which generally occurs at an altitude of 80 120 km above the ground. The particularly bright of meteors is also known as fire meteors. The particles that cause meteors are called meteoroids, so meteors and meteoroids are two different concepts.

Meteorites in space are attracted to the Earth's gravitational range and fall off as meteors.

In the vast space of the solar system, in addition to nine planets, dozens of moons, tens of thousands of asteroids, and comets, there are also countless dust and sand grains, which also revolve around the sun like other members of the solar system, and are called "meteoroids". Meteoroids pass through the Earth's atmosphere, rub against the atmosphere and burn to emit light, which is what we see as the "meteor phenomenon".

Meteors are the phenomenon that some small dust or debris in interplanetary space is attracted by the earth and violently rubbed and glows in the atmosphere. Meteors are usually very small, and the meteors we can see are usually only a few millimeters or so. A meteor shower is the Earth's orbit through a comet or some asteroid, and these.

The landscape that occurs when a "cloud of particles" ejected by celestial bodies meets, and a large number of small debris meets the Earth.

Meteors rub in the atmosphere to produce sparks that produce light, so the meteors you see are bright.

Meteors are a kind of objects in the universe, they wander in the universe, they may have orbits, or they may be walking destination flights, because of flying in the universe, due to the law of gravitation, it will be subject to various forces of attraction and repulsion, its direction of motion may change, when running near the earth, because the strong attraction of the earth is enough to make them change their orbit, they will run to the earth, when flying into the atmosphere, friction with the atmosphere to produce light and heat, and at the same time they are gradually burning out. It seemed to us that it drew a beautiful arc in the sky.

If it hasn't burned out by the time it reaches the ground, it's a meteorite (there are two types of meteorites and meteorites).

That's why there are so many craters on the Moon, and since the Moon has no atmosphere, it hits a crater.
