Most of us have seen the movie Armageddon, or at least know the plot; an asteroid is on a collision course with the Earth and could spell certain doom and disaster for the planet and its inhabitants. Popular television shows on The History Channel and other stations show a 'what if' scenario should an asteroid or large meteor strike happen in populated places, and makes for good entertainment. The reality is, these kind of things have happened many times in the 4 billion year history of Earth. Billions of years ago as the universe was being born, hundreds, or thousands, of meteors and small asteroids struck the planet on a regular basis as planetary bodies slammed into one another, raining the rocky debris into the atmosphere. Most smaller meteors or meteorites are torn apart and disintegrate due to atmospheric friction, but occasionally, some penetrate through the volatile conditions and strike land.
