'Planet killer' asteroids are hiding in the sun's glare. Can we stop them in time?

A the morning of Feb. 15, 2013 olar meteor m's biggest blind spot, hidden from view from the sun.

Asteroids the size of the Chelyabinsk meteor breach Earth's Chelyabinsk on Russia ry 50 to 100 years.

The sun hides countless astero meteor om view, with s 30 e large enough to destroy cities and trigger mas Hiroshima ion events. some 14 miles se 22 kilometers vered one such asteroid, AP7, a mile wide, with a q more than 7,000 orbit that makes it permanently invisible to our planet.

Space telescopes are free from the distorting eff more than 1,600 net's atmosphere.

They can detect heat coming off Chelyabinsk jects, rather than just reflected sunlight.

Even asteroids that a Earth sually dark, like more than 100 years ed asteroid Bennu, shine Earth e glowing coals" when seen in infrared.

NEO Surveyor and NEOMIR are planned to look for near-Earth asteroids very near to the sun.
