Today, the February 15, 2012 DA14 asteroid will fly past Earth. If you are interested in how much it's going to happen to observe such a rare occurrence, it's time: 21 hours 25 minutes to Kiev, or 23 hours 25 minutes Moscow time. In this period he will draw close to the maximum distance to the Earth.
This is a fairly large asteroid, the size of which can be equated to about half a football field. The distance between him and our planet will be 27680 km.
Although there is no danger of a collision, but the space object, called 2012 DA14, definitely caught the attention of NASA.
Don Yeomans (Don Yeomans) of the Programme for the study of near-Earth objects (NASA) (Near Earth Object Program at JPL) celebrates the extraordinary closeness of the asteroid that from the moment when the regular monitoring of the air in the 90s, never such a huge object is not approached so close to Earth.
"In the vicinity of the Earth" a huge number of asteroids, which differ in shape and size, from very small to large. Many of these objects come from the asteroid belt. The program for the study of near-Earth objects helps you to find and keep track of them, especially those objects that are at a record close distance from our planet.
2012 DA14 — a typical asteroid. Its diameter is about 50 meters, it is neither small nor large, and most likely represents a "rocky body." It is estimated the asteroid 2012 DA14 like flies by the Earth every 40 years, and is facing the Earth every 1,200 years.
Don Yeomans (Don Yeomans) indicates that the object of similar size (estimated diameter asteroid is about 50 meters) was the cause of the Arizona edge? Tera when the object hit the surface of the earth about 50,000 years ago. "This asteroid was made of iron, making it a particularly powerful punch."
In 1908, exploded over Siberia a space object, a comet or asteroid, known as the "Tunguska meteorite". It is known that the effect of the explosion were felled trees more than 80 meters. Scientists are still studying the effects of this phenomenon.
"2012 DA14 will not hit the Earth. The orbit of the asteroid studied sufficiently, which excludes the impact "
Still, the distance will be close. NASA will track the movement of the asteroid, which will be closer to Earth than many satellites.
Radar NASA's Goldstone Solar System Radar in the Mojave Desert will track the asteroid from 15 to 20 February. The observations will allow not only more accurately determine the orbit of the asteroid, but also to predict the possibility of future similar meetings, as well as to determine the physical properties of the object: size, spin, and reflective.
