Have you heard about news or even rumors about comets and asteroids that hit the Earth and how their impacts affect our planet? Have you ever asked yourself if how often does a comet or an asteroid hit the Earth? Well, recent advances in Space Technology have allowed scientists coming from different background such as physics, chemistry, biology and geology to collaborate in studying the Near-Earth Objects (NEO) such as comets ad asteroids. With more powerful telescopes and space probes, the study of comets and asteroids provides more clues about the origin of our solar system. Over the past few years, amateurs and professional astronomers have discovered several NEOs that came close to Earth and one of them is the Asteroid 2012 DA14. It made a very close approach to Earth as it orbited the Sun on February 16,2012 (Philippine Time). In the morning of the same day, an asteroid entered and exploded over Lake Chebarkul in Russia hurting about 1,000 people in the process. These two events triggered superstitions, fears, and doomsday prophecies held by different cultures. But do these things have scientific basis?
