An aircraft-carrier sized asteroid known as 2005 YU55 is expected to safely fly past Earth this afternoon at a distance slightly closer than the moon's orbit.
Scientists at the Jet Propulsion Laboratory (JPL) have been tracking the asteroid using the Deep Space Network antenna in Goldstone, California. At its closest approach to our planet, at 3:28 p.m. PST, 2005 YU55 will be no closer than 324,600 kilometers (201,700 miles) as measured from the center of Earth. Still, today's approach will be the closest of a space rock of this size since 1976, and it offers scientists a rare opportunity to observe a nearby asteroid.
