the next century, there were no asteroid collision

Near earth asteroid, 2005 YU55, images can be perpetuated by the Arecibo Radar Telescope in Puerto Rico on 19 April. Data collected during the period of 2005 YU55 Arecibo observations made Near-Earth Object Program Office at the Jet Propulsion Laboratory is owned by the American space agency (NASA) can find the space rock's orbit properly. Based on that data, scientists have dared to get rid of all the opportunities that an asteroid hit the earth in 100 years.

At the time of the radar echo image was taken, the space rock is located 2.3 million kilometers from earth. Although blurred, the picture resolution of 7.5 meters per pixel. It is revealed that in 2005 YU55-sized spherical objects 400 meters.

Radar would not only supply data on the dimensions of the asteroid, but also the exact location of the object in space. By using the capabilities of high-precision radar astrometri Arecibo, scientists are able to reduce the uncertainty of the orbit YU55 up to 50 percent.

"We never classify 2005 YU55 as a potential threat," said Steve Chesley, a scientist at the Near-Earth Object Program Office. "Before the Arecibo radar passed on April 19 to 21, we have eliminated almost all the objects near the earth as the possibility of collision. But there are some that still show the possibility of collisions. After entering the data from Arecibo, we can remove all possible collision until 100 years to come. "

With more observations in the future, scientists could possibly know the orbit of 2005 YU55 accurately.

NASA to detect, track and characterize asteroids and comets that pass close to Earth using space telescopes and telescopes located on Earth. Objects near the Earth observation program, or more often called "Spaceguard", found objects, the characterization of their group, and designing their orbits to determine whether a foreign object that can be potential threat to our planet in the future.
