The event that was to be remembered occurred on June 30, 1908, when an asteroid of 30-50 meters in diameter penetrated into the atmosphere and exploded at 8 kilometers on Tunguska, Siberia.

The explosion instantly released an energy equivalent to that of a thousand atomic bombs of the "Hiroshima" type and destroyed a large forest area.

Statistically, an event of the kind of Tunguska can happen once every 200 years: more than a catastrophe that has never been known much, the Asteroid Day is a warning to humanity because the clash between Earth and an asteroid , Even small in size, can cause a catastrophe.

Thanks to the telescope network that surrounds the sky, 1,000 asteroids have been discovered since 1898-2000, but in recent years the number is growing at a rate of 1,000-2,000 per year. Not everyone is dangerous to the Earth, but the warning is, in the end, that unknown objects that span space near Earth are so many.
