Now that everyone's nerves are on edge following the break up of a small asteroid over Chelyabinsk, Russia this morning, we now turn our frayed attention to Asteroid 2012 DA14. NASA is scheduled to start its audio commentary at 11:00 AM PST (2:00 PM EST). The live broadcast will integrate real-time animation to show the location of the asteroid with the Earth, along with live or near real-time views of DA14 from observatories in Australia.

The asteroid's closest approach to Earth will happen at approximately 11:25 AM PST (2:25 PM EST), and it'll be about 17,150 miles (27,600 kilometers) above Earth's surface.

The commentary will be available via NASA TV and streamed live online at ustream (above).
