After this morning’s Russian fireball, we’re all sitting on the edge of our seats, but the fireball and 2012 DA14 are unrelated asteroid fragments on very different paths. One made a beeline directly to Earth, the other will safely pass 17,150 miles away around 1:24 p.m. (CST) today. The latest estimates on the Russian meteoroid’s size before it broke it up in the atmosphere put it around 50 feet across with a weight upwards of 7,000 tons. Today’s asteroid in contrast is about 150 feet end-to-end and tips the scales at 209,000 tons.
Amateur astronomer Dave Herald of Australia has been busy taking pictures of 2012 DA14 through his telescope overnight. His photograph shows the asteroid as a trail against the starry backdrop as it moved northward during the 4-minute time exposure. Herald will be providing an online feed with his observations and photos for NASA later today.
If you’d like to hear commentary and see real-time pictures of the flyby (from Dave and others), check out NASA TV’s live stream beginning at 11 a.m. Central Time and continuing through the afternoon. Undoubtedly you’ll learn more about the Russian fireball there, too. When pictures are shown, the asteroid will look exactly like a star, because you’re looking at a small object many thousands of miles away.
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 8 p.m. CST this evening when the asteroid is visible in a dark sky over the U.S. You can view the feed and ask researchers questions about the flyby via Twitter HERE.
And don’t forget to take a virtual ride-along with the asteroid available HERE. Images are updated every 2 minutes. Enjoy the show!
