On snowless pre -holiday days, Colta.ru shares the overall alarm and offers readers a certain number of forecasts for the future. Bad and good - who likes what more.
1. Asteroid Apophis: 2029On December 13, 2029, asteroid 99942 Apophis , a space stone with a diameter of 325 meters, will enter the atmosphere of the Earth. When impact, he will cause an explosion with a capacity of 750 megatons, or 37 thousand Hiroshosim-15 times more than the “king-bomb”, the most powerful of the hydrogen bombs blown up on the planet. The consequences for those who survived the explosion? Perennial nuclear winter on the entire planet from the dust raised into the atmosphere, which will weaken the sun's rays.
When the asteroid was only opened in 2004, astronomers assessed the probability that everything would be so, at 2.7 percent. Then the trajectory of the heavenly body was specified-and they said that humanity has seven years in reserve: the largest risk of a collision falls on the 2036th. And now they are already discussing the meeting of the planet with an asteroid in 2064, and the chances have decreased to 1 to 149 thousand.
