Recently, some science enthusiasts joked: "please mark the April 13, 2036 on the phone calendar with a solemn mood. From the perspective of astronomy, this is a very special day, on this day, a diaoman asteroid may encounter with the earth." If that is true, that day will probably be the end of the world! "
This is not alarmist, the asteroid science lovers mentioned is "apophis". In early 2004, Hawaii experts engaged in related research on this asteroid's whereabouts was quite worried, it may bring great disaster to the earth.
Apophis "is the symbol of" God of destruction "in Egyptian mythology, the planet of diameter of about 390 meters. According to astronomers, if it moves smoothly with the current track, it will probably hit Earth in 2036.
Although the planet is small, the power of the planet can not be underestimated. The results of laboratory simulation show that the energy released by "apphis" on the earth is 100 thousand times higher than the energy released by Hiroshima atomic bomb, which is amazing.
At that time, it is expected that several thousand or tens of thousands of square kilometres will be seriously affected. The dust produced during the collision will be enveloped in the air, which is likely to bring fatal effects to the earth's atmosphere and the entire ecosystem. If so, human beings may face the fate of dinosaurs 65 million years ago.
For this reason, we need to be vigilant and pay close attention to the trend of this asteroids. If it is a little wrong, we should make necessary human intervention to avoid irretrievable situation. For the "Apophis", need to be cautious but not overly worried, in today's advanced science and technology support, scientists can use artificially change the asteroid's orbit and other methods to avoid collision with earth.
