Humans may A great calamity is at hand. again?
Please circle in the calendar on April 13, 2036, the day of the asteroid is likely to hit the earth, once the tragedy, it will become a lot of people on earth at the end of the world! Recently, San Francisco in the United States at the AAAS annual meeting, scientists have issued such a warning.
A man named Apophis 390 meters wide asteroid could collide with earth on 2036, released by the Hiroshima atomic bomb explosion 100 thousand times higher energy, thousands of square kilometers area will be directly affected, and released to the ecological dust in the atmosphere will affect the whole earth.
On April 13, 2036, the day of the asteroid is likely to hit the earth
Apophis is a demon named in Egyptian mythology. In Egyptian mythology, Apophis is evil and destruction of ancient magic, its purpose is to make the whole world into permanent darkness. Recently, astronomers will be a being from outer space to the Earth Asteroid is named for Apophis.
As the devil's name, it is because the asteroid will bring disaster to human hitherto unknown threats. This asteroid formerly called 2004MN4, it is found that scientists in June 2004, has a diameter of about 390 meters wide.
Near Earth Asteroid collided with earth
Near earth asteroid colliding with earth, it is only a matter of time, rather than the will of the problem. Many smaller space objects are melted into the earth's atmosphere, and therefore could not collide the earth.
However, more than 1 kilometers in diameter asteroid colliding with earth, hundreds of thousands of years every time, more than 6 kilometers in diameter asteroid colliding with earth, hundreds of millions of years every time, the impact of this will lead to the extinction of the disaster. This time we face is a late big guy.
And now, the key problem is Apophis will hit the earth?
NASA scientists track after checking found that the threat level is the highest in history, Apophis 2029 years and will pass the earth, but it will be in 2036 years to visit the earth, and may break through the atmosphere and the earth!
Apophis Torino is currently ranked in grade fourth, 10 grade means inevitable destruction of global collision. Is the highest risk level of Apophis found in the history of the earth and asteroids, it collided in 2036 the probability of up to 37!
When Apophis in April 13, 2029 after a near earth, the earth's gravity will change its orbit it will again in 2036 to visit the earth, and the earth collided.
Apophis will hit the earth
Two, then, the earth we should do?
Only change hit the asteroid's orbit, the earth scientists have proposed many theoretical methods. Such as: the European Space Agency's advanced concepts team designed by a row of satellite or rocket propelled asteroid hit the track method. Scientists are most interested in, most likely, is sending a spacecraft and asteroids violent collision, thus changing its direction.
We look at
