Close encounter: Asteroid flies close to Earth; experts say there’s no chance of impact

LOS ANGELES — An asteroid as big as an aircraft carrier zipped by Earth on Tuesday in the closest encounter by such a massive space rock in more than three decades.
Scientists ruled out any chance of a collision but turned their telescopes skyward to learn more about the object known as 2005 YU55.
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.
