House-size Asteroid Buzzes Earth Day After Its Discovery

摘要

An asteroid the size of a house zoomed by Earth March 16, flying within the orbit of the Moon just one day after astronomers first spotted the space rock, NASA said. The small asteroid 2011 EB74 was about 14 meters across and posed no threat of hitting Earth, since it was too small to survive the trip through the planet's atmosphere. Instead, the asteroid passed Earth at a distance of about 327,000 kilometers when it made its closest approach at 5:49 p.m. EDT, NASA officials said.
