Asteroid hurtles towards earth. Scientists were today, January 4th, 2014, warning of a possible asteroid collision with the Earth.
A newly discovered asteroid will pass very close to Earth on Sunday, NASA says. The space rock is estimated to be 60 feet (18 meters) long. It's expected to fly over New Zealand about 2:18 p.m. EDT (11:18 a.m. PDT / 18:18 UTC.). It won't hit Earth or any of the thousands of satellites orbiting the planet, NASA says.
