Sounds menacing, doesn’t it? But let this not be a hindrance your celebration on Valentine’s Day. An asteroid changed his plans and lingers a little, postponing its approach to Earth by 15 February. Yes, on this February day, an asteroid intends to fly in substantial proximity to our planet. The distance he approaches will be 27,680 kilometers. And this is a record close distance, according to NASA, since even GPS satellites rotate in an orbit farther from Of the earth. This asteroid has a very significant size. His the value is approximately half of the football field, which is about 50 square meters. Scientists have already given him an alphanumeric designation. This is 2012DA14. NASA spokesman Don Jomansiz said what are the chances of a GPS satellite colliding with this space the wanderers are very small, since the trajectory of his flight does not cross almost none of the satellite’s orbits. At a size that is about half the football field, an asteroid cannot be called great. But you will not name small either. He is educated throughout probabilities made of stone, not metal, like the one that collapsed in 2003 in American Arizona, forming a crater the size of one and a half kilometers. The severity of the metal “pebble” increased strength, with which there was a collision. But in size it resembled current, and the area of destruction then was 83 kilometers. Mr. Jomansiz assessed the frequency with which asteroids approach the Earth and fall on it. According to Jomanziz asteroids fly near the blue planet about once every 40 years. A clashes occur even less frequently: once every 1200 years. So what are we still celebrate Valentine’s Day more than once, rejoicing in each other and continuing life on earth. And although the fall of an asteroid of this size would not have fatal consequences for our planet, but still it’s impossible not to recall that an asteroid that exploded in the earth in 1908 atmosphere over Siberia, destroyed hundreds of hectares of forest.
