The asteroid to buzz Earth Friday


An asteroid the size of a small office building is due to the genius of the Earth last Friday, traveling more than 28,000 kilometers per hour.Weighing about 130,000 tons, 2012DA14 obtained within 28,000 km of Earth. “This is well within the geostationary ring, where many communication satellites are”, says Detlef Koschny, responsible for near-Earth objects of the ESA office space situational awareness. “There is no danger to satellites, however, because the asteroid will come” from below “and not cut the geostationary belt.” The asteroid was discovered by observing the sky of La Sagra, on February 22, 2012. Its small size and previously unknown orbit meant that was discovered only after having flown past Earth at about seven times the distance of the moon. “While there is absolutely no chance that this particular asteroid hits Earth, highlighting the dangers of so-called” near-Earth objects “of which about ten thousand of the expected million have been identified,” says astronomer University of Hertfordshire Dr. Mark Gallaway.” By monitoring their movements will be able to improve our understanding of these potentially hazardous objects”.The asteroid is too faint to be seen with the naked eye, but will be visible with binoculars at about 20:00 GMT. Its closest approach to Earth will be in Australia.”Its orbit can be calculated fairly accurately using the asteroid database NEODyS Europe. These calculations show that a collision with Earth can quite safely exclude at least for this century,” says Koschny.”If this object is made of iron and were to hit our planet, it could create a crater comparable to Meteor Crater 1.5 km near Flagstaff, Arizona, for example. However, I will not.”
