Here's The Effects When Asteroid 2012 DA14 Hit Earth

W-News | Here's The Effects When Asteroid 2012 DA14 Hit Earth | As communicated earlier, a 45-meter-sized asteroid will cross the Earth to the nearest point pada15 next February and can be seen in the sky Indonesia on Saturday, February 16, 2013 at around 2:26 pm. Like what is the effect if the asteroid hit Earth?

The asteroid named 2012 DA14 to be approached about 27,700 kilometers from the Earth is not going to hit this planet in which we live. But scientists have to guess as to what the effect produced when the asteroid hit the earth.

Reported by LiveScience, scientists said that the collision between asteroid 2012 DA14 with the Earth will create an impact large enough to destroy the land with 80 million trees, or for the entire city of Washington DC following suburbs.

Scientists imagine this is because they equate it with the impact of the object which has a fairly similar size that have occurred in the past.

In 1908, a lump of meteoroids with a weight of about 100 million pounds down over Tunguska, Siberia, which makes the sky on fire and threw the same energy as 185 atomic bombs of Hiroshima and Nagasaki in Japan in 1945.

Lucky, meteoroids crashed in a vacant lot in a remote jungle region of Siberia, so it only kills the lives of hundreds of deer, not humans.

Mark Boslough, a physicist at Sandia National Laboratories, New Mexico, USA, has been using computers to create a theory of the effects of the Tunguska meteorite.

Meteoroid enters the atmosphere at a speed of 539,130 ​​kilometers per hour. No impact crater holes due to pressure and heat waves caused by the explosion. The blast, which made leveling land area 1287 square kilometers.

Scientists who visited the place of the meteorite was found that in the middle of outer space objects crash site is a lot of trees that are still standing but has been deprived of the roots and branches of the skin, indicating the explosion happened so fast.

Meanwhile, the difference celestial explosion with a nuclear bomb is if a nuclear bomb exploded outward in all directions, while the celestial bodies to bring their energy in one direction only.

"There is a concentration of energy directly under the explosion, in contrast to a nuclear bomb," said Boslough.

Scientists in the Near-Earth Object Program Office at NASA's Pasadena, California, estimates that asteroids of similar size will pass this close to an average of once every 40 years.

Mentioned Such crossings can affect Earth, but only once every 1,200 years.
