It is 2036. An enormous asteroid is going to collide with Earth. If it isn`t stopped, it will crash into the Pacyfic Ocean, creating a devastating tsunami. What happens next?
If the asteroid landed in a very remote area of land, there would be fewer deaths at first. However, the explosion would send a huge cloud of dust into the Earth`s atmosphere
We now believe that this was because of a huge asteroid which changed the Earth`s weather. The asteroid was at least 10 km in diameter and landed in Maxico, leaving a hole more than 180 km across.
Nobady lived nearby, so there were no deaths - altough the explosion was so powerful that it destroyed an enormous area of forest and knocked a man off his chair 112 km away
Scientists believe that there are two main options: we could blow up the asteroid with nuclear weapons or we could make it change direction. Both options have their disadvantages. If we blew up the asteroid, it could break into smaller pieces.
Each piece could then be a danger! There are several ideas about how to make an asteroid change direction, but nobody knows which would work best -and it`s impossible to test the technology. And if we failed, we probably wouldn`t get another chance.
