Informing the general public about asteroids and the risks that these bodies represent for Earth is one of the goals of the World Asteroid Day for June 30th.

Another goal of this world day is to take the necessary measures to secure world class crisis communication in the event of a threat to the Earth by nearby bodies. This day should also contribute in the long term to activities that will enable Earth to live and live on it by mapping all nearby Earth (NEO) bodies that could potentially endanger it. For the first time, humanity reminded of the World Asteroid Day 2015.

The date of the new World Day was not accidentally chosen by its organizers – it is related to the phenomenon of Tungus. So far, scientists have been investigating the phenomenon of Tungusky. An example of this was a conference held in April 2019 in Moscow.

On June 30, 1908, in the Tungus area of ​​Siberia, a fireball exploded and exploded. The pressure wave was so strong that it had destroyed 1,200-2,000 square miles of trees, which represented 70-80 million destroyed trees.

The asteroid is a small, firm object in the universe that usually circulates around a larger body, like a star or a planet. The term asteroid comes from the Greek word asteroeidés, stellar. Sir William Herschel (1738-1822), the British astronomer of German origin, used it for the first time in 1802. Soon after the German astronomer and physicist Heinrich Wilhelm Olbers (1758-1840) discovered another asteroid, Pallas, March 28, that same year.

But the exact definition of the asteroid is not fixed. One possible classification of the asteroid is in terms of their size and it says: Asteroids reach an average of more than 50 meters, which differentiates them from meteorites that usually have a rock size or less. This difference is made because the asteroids are large enough to survive the transition through the atmosphere and hit the ground rather intact, while smaller meteors disintegrate through the atmosphere.
