The UN General Assembly declared June 30 International Asteroid Day.
In this way, the UN wants to draw the public's attention to the danger of a possible collision of an asteroid with the Earth.
The date is not random – on this day, in 1908, the Tunguska meteorite fell to Earth.
Asteroid (from Ancient Greek ἀστήρ – star and εἶδος – as, in the shape of) is a small planet-like celestial body in orbit around the Sun. Asteroids are also considered small planets or planetoids, with dimensions much smaller than those of the actual planets.
Most asteroids are thought to be remnants of the protoplanetary disk 4.5 billion years ago from which the planets formed, but were not engulfed by them or ejected from the Solar System. Some asteroids have their own moons. Almost all asteroids are in the Asteroid Belt, in elliptical orbits between those of Mars and Jupiter.
