LAURA KNIGHT-JADCZYK AND JOE QUINN
Since the 9/11 attacks, no book has provided a satisfactory answer as to WHY the attacks occurred and who was ultimately responsible for carrying them out - until now.
We're all more aware of these small yet dangerous asteroids that slide right by the Earth because, one, NASA and others are getting better at discovering them on approach; and, two, there was that surprise meteorite that blew up over Chelyabinsk last year (see gallery below), injuring hundreds and generally freaking people out.As happens about 20 times a year with current detection capabilities, a known asteroid will safely pass Earth Wednesday closer than the distance from Earth to the moon.
This asteroid, 2014 DX110, is estimated to be about 100 feet (30 meters) across. Its closest approach to Earth will be at about 217,000 miles (about 350,000 kilometers) from Earth at about 1 p.m. PST (4 p.m. EST) on March 5. The average distance between Earth and its moon is about 239,000 miles (385,000 kilometers).
As the veil lifts and we humans get better at seeing just how much danger is circling our little blue life raft, scientists and enthusiasts are arguing that we need a plan. In response, the U.N. has established the International Asteroid Warning Network for that purpose.An asteroid called 2014 EC that was discovered only last night will pass the Earth just after midnight UTC tonight, sliding past us at a distance of just 56,000 km (35,000 miles) above Earth's surface! This rock is roughly 10 meters across - half the diameter of the Chelyabinsk asteroid. A miss is as good as a mile, as they say, but it shows that there are lots of these things passing us all the time.
