Asteroid 2012 DA14 Passes Very Close to Earth 2013 February
Happy Valentines Day: Asteroid Passes Near Earth
Asteroid 2012 DA 14 is going to pass near Earth in 2013 February 15. I would say happy Valentine's day. Sounds cynic. Yes, it is. But it is not me, who chooses timing. According to the data that NASA gives, asteroid 2012 DA 14 is approximately 45 meters in diameter. The asteroid should pass Earth about 27 000 kilometers above surface. The closest approach should happen about 11:30 PST on February 15. Asteroid 2012 DA14 is the closest object of similar size that approaches Earth in such a short distance. There is no chance that is hits the Earth but it is very close distance. Geosynchronous orbit of telecommunication satellites are approximately in such orbit.
To get more information you can visit NASA website and get all the information about DA14. You can also check some facts, that sounds suspicious. They have videos also, showing the asteroid and explaining its orbit.
How asteroid 2012 DA14 was discovered?
The asteroid 2012 DA14 was discovered in 2012. The asteroid orbits the Sun at almost the same orbit as the Earth do. It's orbit is tilted 12 degrees, comparing to Earth orbit. The asteroid was discovered in Spain on February 22, 2012. The team of astronomers were working with La Sagra Sky Survey that is operated by Astronomical Observatory of Malorca. The telescope then was recently updated with new camera, that allowed the detection of fast moving objects. This allowed asteroid 2012 DA14 to be detected. This asteroid was not the only near Earth object that was detected using La Sagra Sky Survey. There were more that ten objects found, including previously unknown comet.
At the moment of discovery the asteroid was moving about 4.3 million km away from Earth. After the discovery this object got many attention from NASA and other astronomers. Actually all near Earth objects are examined accurately. This allows identifying potential threats of the impact. There some statistical data that shows that similar objects fly near Earth in such a short distances once in 40 years.
What do you think
Do you think meteorite shower in Russia is related to DA14?
Is Meteorite Crash in Russia Related to DA14?
On Friday morning, 2012 February 15 meteorite crashed in Russia. There two opinion about this meteorite shower that was followed by explosion so strong, that blown-out the windows.
Two main discussions are going on about this meteorite crash. The ESA (European Space Agency) released a message on Twitter that there is no connection between meteorite crash in Russia and asteroid 2012 DA14. It seems that the the meteorites that crashed in Russia has completely different trajectories, comparing to DA14. At the same time, there are astronomers that claim that this meteorite crash can be connected with DA14. It could be debris preceding the asteroid.
My personal opinion is indefinite. I believe that there too early to make the conclusions. Many calculations must be done to prove if there is a connection or not. Official reports should be waited for to know for sure.

How many there are near-Earth objects?
Asteroid 2012 DA14 successfully flew-by Earth on 2012 February 15. It was only 27 000 kilometers away from Earth. It is the distance in which telecommunication satellites fly. The objects, that has orbits that allow them to get into proximity with Earth are called near Earth objects, or simply NEO. Sounds like that guy from Matrix, but it is not. There are few thousand objects that are NEO. These objects are asteroids, comets, meteoroids and others. These objects has a huge interest of astronomers because they have a potential danger to hit Earth someday. Not all NEOs are dangerous. Near Earth objects that can approach threatening close to Earth are called potentially hazardous objects, or PHOs.
