Deep Impact

A boy discovers a comet, and it is going to hit the Earth. A group of astronauts are sent on to the comet and a nuke has been put deeply into the comet. The mission has failed and the comet has been blown into two pieces.  The first one hit the Atlantic Ocean, it has made a circle of waves as high as 1000 meters and has destroyed most of the surrounding cities. And the second larger one has been destroyed by the astronauts as they crashed into it.
