Will an Asteroid Hit Earth in 2012?

If we talk about the end of the world that is said to be occurring in December 21 2012, the one theory from the theories that tell us how the earth will destroy is that the earth will be hit by a huge asteroid. It says that thousands of years ago an asteroid hits the earth and being a reason to kill the dinosaurs and the same thing is coming means an asteroid again comes to hit the earth. Is it true or an idea?? What the truth behind this?? Is it only a fear of human being or our earth is really going to be destroyed by an asteroid??

   You will be shocked if you listen that this is true that an asteroid is coming towards the earth they may be reached till December 21 2012 on earth.  This asteroid is named as Toutatis which is quite near. It is now only 4,140,000 miles away from the earth that is 18 times of the distance from earth to the moon.

  Some scientists says that Toutatis will not hit the earth in 2012 but there is another asteroid (Apophis) which will come closer to the earth in April of 2027 which is 22,000 miles away from the earth. No one sure what will happen but if an asteroid is really comes towards the earth then it totally destroyed our earth.
