What is the meteor?

Meteor is a strip of bright light that can be seen from the ground when meteorite enters the atmosphere. The real object entering the atmosphere is called meteorite and is usually a piece of asteroid. The term meteor only concerns the image created by this item - the bright light of the cascading from the sky - often referred to as the falling star .

The bright meteor light is the result of the heat produced by the meteorite that enters the atmosphere. Rather than friction, this heat is produced by RAM: pressure exerted on the body moving liquid medium. This pressure warms the meteorite and the air around it to the extent that the meteor image can be seen from the ground.

Although meteorites are often referred to as meteors or meteor rocks, this use is not technically correct. While most meteorites come from asteroids, it has been speculated that some may come from comets and others probably come from the moon or Mars.Meteorites discovered on Earth are often categorized as fall or Find . The fall is a meteorite discovered after someone is evidenced by the meteor and sees the meteorite to fall to the ground, while the finding is a meteorite that is found after the meteor has been witnessed when he was not witness.

At any night you can see so many meteor in an hour and during a meteor shower, this speed can increase up to a hundred per hour. Although many meteorites enter the Earth's atmosphere every day, most of them are too small to cause a visible image or to get to the earth's surface. Although the meteorites enter the atmosphere at incredibly high speeds, buying 40 miles (70 km) per second, they usually slow down to just a few hundred miles per hour and reach the Earth's surface with a small impact. Extremely bright meteors can be called fiery balls or bolides. While Tamjsou different regulations on what degree of brightness represents a fiery ball, it is clear that they are an impressive look, but rare to see.
