Get ready for the flyby of asteroid 2012 DA14, which will be closest to Earth at 2:25 p.m. Friday. It's the miss that will be a hit for online video.
By close, we mean 17,150 miles away in space, but it is the closest encounter with an asteroid of that size scientists have ever known about in advance. There is no chance it will hit Earth. And it's path has been known to owners of satellites, so it's unlikely to strike one.
While the asteroid is about 164 feet wide and weights 130,000 metric tons, you will be unable to see the asteroid in the sky in East Tennessee; viewers in eastern Europe, Africa, Australia and New Zealand have the best chance with telescopes , but it's moving fast. You can watch it via live video streams.
NASA Television will provide have a special half-hour fly show at 2 p.m. on Friday. The half-hour broadcast from NASA's Jet Propulsion Laboratory in Pasadena, Calif., will include real-time animation to show the location of the asteroid in relation to Earth, along with live or near real-time views of the asteroid from observatories in Australia, weather permitting.
A Ustream feed of the flyby from a telescope at NASA's Marshall Space Flight Center in Huntsville, Ala., will be streamed for three hours starting at 9 p.m. To view the feed and ask researchers questions about the flyby via Twitter, visit: http://www.ustream.tv/channel/nasa-msfc .
NASA will also have commentary from astronomers in Australia and Europe and near real-time imagery, weather permitting, beginning about noon and continuing through the afternoon at http://www.ustream.tv/nasajpl2 .
