What are meteorites and why do they exist?

Considered as the debris of the formation of the solar system, the asteroids are rocky bodies of different sizes that revolve around the Sun, which lives mainly between the orbits of Mars and Jupiter, in the " These asteroids unlike the planets, are not round, have irregular shapes and there are never equal compounds of different types of rocks and sometimes clays, metals such as nickel or iron.

The National Administration of Aeronautics and Space (NASA), specified that the asteroids they are the remains of the formation of the solar system that began four thousand, 600 million years ago when a large cloud of gas and dust collapsed.

Most of the material fell to the center of the cloud and formed e Sun Some dust condensed in the cloud dev Intense planets, objects in the asteroid belt have never had the opportunity to be incorporated into the planets.

Because the asteroids were formed with other objects in the planetary system, these space rocks can provide scientists with information about the history of the planets and the Sun. The US space agency explained that the asteroids take three to six years to perform a sun tour.

An asteroid can be pushed, out of its orbit, by the gravitational pull of a big object like a planet. Once the object is captured by the gravitational force of a planet, it can become a satellite of the planet, so both will follow the same path around the Sun.

Astronomers believe that if it is not for Jupiter, it exerts a gravitational force on the asteroids in the belt, the inner planets such as Mercury, Venus, Earth and Mars would be bombed constantly by the great asteroids said NASA.

While the asteroids are the remnants of the formation of the solar system, when these collide, other smaller star bodies are generated, called ] meteoroids or meteorites

In this way, if a meteoroid approaches Earth sufficiently and enters its atmosphere, it vaporizes and becomes meteor to produce lightning. light in the sky, which are known as " shooting stars ". However, sometimes meteoroids do not vaporize completely in the atmosphere of the Earth and reach the ground under the name of Meteorites .

Like asteroids comets orbiting the sun, however, the latter seem to contain a greater amount of ice and gas. The US space agency explained that when the orbit of a comet is directed towards the sun, ice and dust begin to evaporate, this phenomenon produces the tail of the comet.
