The day after Valentine’s Day, an asteroid will approach the Earth. Not to hit it, but the space rock along 150 feet or 45.7 meters will be within a very close relative.
So close, Asteroid 2012 DA14 will drift under man-made satellite in orbit around our planet. The distance is only about 17,000 miles or 27358.8 miles, closer than geostationary satellites are launched humans into space – a distance of 22,200 miles or 35,727 kilometers above the Earth.
Although relatively small, if it gets slammed into the Earth, the asteroid could cause havoc. Because, when pierced it will produce energy equivalent to 2.5 megatons of TNT. Although there will trigger the apocalypse, enough power to destroy life in the city area of Greater London (Greater London).
The bad news again, 2012 DA14 just one of the 500,000 stones that fly near Earth space.
Clearly visible from Indonesia
Although close, the asteroid can not be seen with the naked eye. According to the United States Space Agency (NASA), 2012 DA14 is not bright enough. Must be seen through a telescope or binoculars.
NASA called, the asteroid will be shot from the night sky in the southern hemisphere, heading north toward morning. Distance of closest approach to Earth will take place February 15 at 19:26 UTC or 2:26 o’clock pm, February 16, 2013.
After four minutes the closest distance to the Earth, there will be a good opportunity to enter the Earth’s shadow 2012 DA14 about 18 minutes,
When moving quickly to the north which went in the morning, 2012 DA14 will quickly fade with sunlight.
According to NASA, Indonesia is the best place to observe the 2012 DA14, while sky watchers in Eastern Europe, Asia, and Australia can enjoy the view while floating space rock with a speed of 17,400 mph.
Will Hit Earth
2012 DA14 was discovered last year by astronomers at the observatory of La Sagra Sky Survey, near Granada, Spain. This year is the distance of closest approach to Earth in at least three decades.
“In the future the possibility of colliding with Earth in 2012 DA14 can not be ruled out. Though almost impossible, the probability is greater than zero,” said Dr. Gerhard Drolshagen, observers object near Earth from Space Situational Awareness (SSA) European Space Agency, as published by the Daily Mail, Monday (02/04/2013).
The asteroid will approach the Earth back in 2046, the relatively close distance of the 37,000 miles or 59,545 kilometers.
Then 97 years later, precisely on February 16, 2110, will be re-approaching asteroid. It was then that he was likely to hit the Earth. Although the likelihood is very thin, ie 1:7.692.308.000.
Meanwhile, as published in Los Angeles Times, opportunities DA14-sized asteroid hit the Earth only once every 1,200 years or more. Similarly, NASA spokesman revealed, David Agle.
The last time that happened was in 1908 in Tunguska, Siberia. At that time, on June 30, 1908, at 07:14 local time, an explosion occurred in the interior of Krasnoyarsk Krai, Russia. Its power reached 1,000 times the Hiroshima atomic bomb.
The result was incredible. A total of 80 million trees covering an area of 830 square miles burned. Fortunately, no casualties. Because the site of the blast away from the settlement.
