If you look at the night sky, it’s entirely possible that you’ve seen meteors and meteor showers along with stars, even if you never noticed them. Well, this the size is small Does this mean?

Let’s explain.

The term meteor actually refers to a streak of light caused by a piece of space debris burning in the atmosphere.

Also pieces of meteoroid debris that reach the surface of the Earth or another planet Meteorite remains were found in the rubble It is mentioned. Meteorites have a fairly long range. But most of the debris that Earth comes into contact with is dust from comets passing through the solar system. This dust consists of very small particles.

Meteoroids, on the other hand, enter the atmosphere at extremely high speeds. This speed is average, 11 to 72 kilometers per second between. In the vacuum of space, they can move at this speed quite easily because there is nothing holding them back.

Moreover, the Earth’s atmosphere is full of matter, which causes a moving object to move causes great friction. This friction generates enough heat to bring the surface of the meteoroid to the boiling point, causing the meteoroid to evaporate layer by layer.

Let’s talk about how big a meteoroid has to be to reach the Earth’s surface.

Most meteoroids that reach the surface are strangely small. So much so that their size is microscopic dirt or dust particles is on Furthermore, estimates of the minimum size for meteoroids large enough to form visible meteors vary.

The reason for this is that factors other than size are also effective. For example, the entry velocity of a meteoroid is affects the chance of reaching the surface because this speed also determines the amount of friction. But usually a meteoroid has to be the size of a marble to reach the Earth’s surface.

Because smaller particles are about the size of the Earth In the atmosphere 80 to 120 km above burns.
