CALIFORNIA – Scientists are studying the details of an asteroid impact that pierced through the Earth at the beginning of the formation. they also reveal the planet Earth long ago been hit by an asteroid measuring 40 kilometers in diameter. Asteroid with a diameter of 40 Km ever hit the earth

“This is the first strong evidence that actually happened. Some of the asteroids that we infer, have a diameter of 40 kilometers. Size is much larger than any asteroid that killed the dinosaurs approximately 65 million years ago with a diameter of approximately 12 to 15 kilometers,” says scientist Earth and Atmospheric from Purdue University, Jay Melosh, as reported by Machinelikeus, Friday (27/04/2012).

Scientists believe the beginning of the creation of planet Earth followed by the collision of an asteroid collision, which occurred approximately 35 million to 3.5 billion years ago. At the time, believed to give impact asteroid impacts significantly on survival of extinct animals, extinction of the dinosaurs.

In addition, scientists are also trying to apply a new method to uncover information from the layer of small rocks called spherules. The rock layer is created from the collision of asteroids that hit the planet Earth. Clash of the rocks until it evaporates into the air. Then, tiny droplets of molten rock solidifies again and fell back to earth as a thin layer. Asteroid with a diameter of 40 Km ever hit the earth

As a result, the particles are round or oval rocks that have embedded lines on the planet Earth. That is what has been studied and analyzed by scientists to obtain information on the effects of asteroid impacts on planet Earth at the beginning of the formation.

That said, the period of this asteroid is affected by changes in the solar system that changes the trajectory of the asteroid. Trajectory which lies between Mars and Jupiter was able to send the asteroid landed on planet Earth. “What we do is provide a basis for understanding how to interpret the layers in terms of size and velocity of the asteroid,” he explained.
