“It will be the nearest recorded brush with a space rock so large, NASA scientists said Thursday.
The good news: There’s no chance of an impact. At its closest, asteroid 2012 DA14 will pass about 17,000 miles above Earth.
The bad news: A million other potentially dangerous — and unknown — city-killing space rocks are out there, and one of them could be on a collision course with Earth. Critics say NASA and other space agencies are not doing enough to scan for these threats.
Satellite operators said they were monitoring the asteroid but expected it to safely cruise through a belt of satellites that are about 23,000 miles up.
The asteroid was about 150 feet wide. Its closest approach will occur at 2:24 p.m. Eastern time on the 15th.
