NASA released today what it described as the highest-resolution
images ever generated by radar of a near-Earth object as a huge asteroid

The asteroid, known as 2005 YU55, is as big as an aircraft carrier. It zipped by Earth on Tuesday in the closest encounter by such a massive space rock in more than three decades.
Its closest approach to Earth was pegged at a distance of 202,000 miles at 6:28 p.m. EST. That's just inside the moon's orbit; the average distance between Earth and the moon is 239,000 miles. Full Read
