All these space objects can crash into the Earth, a collision with them threatens the planet with a global catastrophe, writes Газета.ru.
These asteroids are located at a distance of about 45 million km from the Earth's orbital path. Of the 400 new objects, 50 have a width of more than 140 m. An asteroid of this size could destroy a city. One asteroid also has a width of more than 1 km, which in a collision could destroy a much larger area.
It is noted that the network of stations that detect dangerous meteorites was deployed in 2004 after the discovery of the asteroid Apophis, which with a high probability could collide with the Earth.
