Astronomers are tracking an asteroid about the size of an aircraft carrier that on Tuesday will pass by Earth, within the moon's orbit, in the closest approach of such an object in a generation. The 1,300-foot-wide asteroid, known as 2005 YU55, poses no hazard, experts at NASA's Jet Propulsion Laboratory said. They are monitoring the spinning space rock by radar as it nears and eventually speeds past Earth at a distance of 201,000 miles. The asteroid is going 29,000 miles per hour, according to astronomers at the University of Arizona. Asteroid to Pass Close to Earth - WSJ.com
