An asteroid came very close and was discovered a few hours after the Earth World of various DW

European Early Warning System: There are approximately 10,000 small asteroids hovering close to the Earth and potentially dangerous to humans and anything on the surface of the Earth. The European Space Agency is setting up an early warning system in the Italian Frascati region. The data and information will be collected with the help of telescopes such as those shown in the photo and located in the Spanish island of Tenerife located in the Atlantic Ocean.

The importance of the early warning system for asteroids: To understand the importance of the early warning system that monitors asteroids approaching the Earth, it is necessary to know the destructive force of the meteorite that hit the ground near the Russian region of Chelyabinsk on 15/02/2013, rewarding the destructive force of 100 to 1000 km Tons of explosive TNT and about 1 500 people were injured in the area. ;explosion.

Before its combustion in the Earth's atmosphere, the diameter of the Chelyabinsk meteorite was estimated at 20 meters, there remains only one rock weighing only 1 kilogram, which fell to the ground, creating a wide range of 6 meters in the ground ice.

There was an asteroid named "2012 DA14" which was much more dangerous. It weighed 130,000 tons and the asteroid had only traveled 27,000 kilometers from the Earth on the same day as the Chelyabinsk meteorite on Earth. This distance makes it closer to Earth than some of the satellites orbiting around it.

Many other asteroids and comets are expected to approach the Earth within a year. Scientists observe it and watch it closely, as smaller rocks from these comets and asteroids can be dangerous for humans.

Comets and Meteors: The fireballs are composed of a cloud of gas, a large tail of gas, pebbles and dust particles. When the comets of comets enter the airspace, they heat up to a high temperature of 3000 ° C, start to shine and become like stars.

A meteor shower is a meteorite heavy rain that rises in the summer and can be seen with the naked eye as it penetrates deep into the ground, originally from the Swift Tuttle, discovered in the nineteenth century. Each summer, these meteors express the surface of the Earth's atmosphere, called "meteorites", which is relative to the asteroid Perseus or Parshaus, the "head of the ghoul" in ancient Greek mythology.

Meteorite dust burns in the atmosphere and most of its penetrating meteorites are not dangerous and often reach Earth. They are just below the size of a small stone. However, large meteorites can cause a lot of damage. One of the largest craters, caused by the fall of a meteor on the surface of the Earth, located in the state of Arizona, America, of a diameter thousand meters and the age of 50 thousand years.

About 65 million years ago, a giant meteorite from Central America fell on the Yucatan Peninsula (see the simulation of the meteorite fall to the right of the image), creating a crater of more than 180 kilometers on Earth. Experts believe that this led to the extinction of the dinosaurs. According to recent indicators, the extinction of the dinosaurs is due to the collision of two asteroids 160 million years ago.

Meteorites look like burning rocks. The scorched shell of the meteorite forms when it enters the earth's atmosphere where combustion is created by friction and speed. Meteorites have also hit planets other than Earth: NASA's Apollo Opportunity spacecraft has uncovered the first meteorites that struck an extrasolar planet on Mars in 2015.

Not only does the dust of comets rise on Earth, but comets reach the planet. Experts believe that comets are remnants of the formation of planets that appeared during the formation of these and can disappear with secrets about the beginnings of the formation of the solar system.

Most meteorites (99.8% of the 30,000 meteorites) found on Earth have been found to be asteroids. Asteroids come from the formation of planets, but the planets have no atmosphere and their appeal is virtually nonexistent.

After all that has been said, the likelihood that the asteroid will reach the planet Earth over the next 100 years is a very reduced possibility.
