Is there really a meteor in the world?
2. "Meteors are the light trails produced by dust particles and solid blocks (meteoroids) in interplanetary space breaking into the earth's atmosphere and rubbing and burning with the atmosphere. If they are not completely burned in the atmosphere, they are called "meteorites" or "meteorites" after falling to the ground. Meteorites originally moved around the sun, and when passing near the earth, they changed their orbits under the action of the earth's gravity, thus entering the earth's atmosphere.
There are several kinds of meteors: single meteor, fireball and meteor shower. The appearance time and direction of a single meteor are irregular, which is also called accidental meteor. Fireball is also an occasional meteor, but when it appears, it is very bright, like a fire dragon and may be accompanied by explosion, and some can even be seen during the day. Many meteors radiate from a certain point (radiation point) in the starry sky, which is a meteor shower. Meteorite is the remaining part of the larger meteoroid in the solar system that has not completely burned after it broke into the earth's atmosphere. It brings us rich information about the formation and evolution of celestial bodies in the solar system, and it is a welcome uninvited guest. Generally speaking, the density of meteoroids is extremely low, about 1/20 of that of water. Billions of meteoroids enter the earth's atmosphere every day, and their total mass can reach 20 tons. "
