Employees of the U.S. National Aeronautics and Space Administration (NASA) for 100 percent sure what will happen on November 8 large asteroid collision with Earth. "We are quite sure 100 percent sure that there is no such threat," — said Friday Don Emans, Program Manager tracking of near-Earth objects at NASA.
U.S. space agency using radar and radio telescope at Goldstone (California) began monitoring the movement of the object 2005 YU55. Space "alien" has a spherical shape, reaches 400 meters in diameter and wrapped around its own axis once every 18 hours. According to calculations by NASA's Jet Propulsion Laboratory in Pasadena (California), in the coming Tuesday asteroid passes the planet at a distance of 324.6 thousand kilometers (0.85 distance between our planet and the moon). Celestial body of comparable size in the last time was close to the same distance to the Earth as 2005 YU55, in 1976. Following such a "rendezvous" will be held in 2028.
NASA scientists have calculated the hypothetical consequences of direct impact of such an object in the planet. Concussion would be equivalent to an earthquake of magnitude 7, provoked a wave of the tsunami would have reached a height of 22 meters. In the land formed a crater 6.4 kilometers and a depth of 518 meters.
Observation of an asteroid on Friday lasted 2 hours. It will resume on November 6 and will be carried out for four hours a day to 10 November. Second telescope, located in Arecibo (Puerto Rico), will be used to track an object on the stage as close flyby of the planet. This time, it is estimated that there will be November 8 at 15:28 on time U.S. Pacific Coast (November 9, at 02:28 Moscow time).
Space agency intends to get the detailed information about the structure of the object 2005 YU55, the nature of its surface, shape, size, and other characteristics. NASA has a special interest in asteroids, as President Barack Obama has set a task to carry U.S. astronauts landing on one of these sites in 2025. As part of a national program of space exploration by the mid 2030s NASA will send a manned spacecraft to Mars, according to ITAR-TASS.
