Asteroid heads for close call with Earth
SAN DIEGO - Earth is in for its closest brush with an asteroid in recorded history Thursday, when a chunk of rock passes about 43,000 kilometres above the planet's surface.
If there was a collision, the asteroid would likely burn up in the atmosphere, NASA said.
Lisa: I can't believe that extra-thick layer of pollution that I've actually picketed against burned up the comet.
Bart: But what's really amazing, is that this is exactly what Dad said would happen.
Lisa: Yeah, Dad was right.
Homer: I know, kids. I'm scared too!
