Asteroid flyby on Friday: Where and when to watch it online

Graphic depicts the trajectory of asteroid 2012 DA14 during its close approach, as seen edge-on to Earth's equatorial plane. The graphic demonstrates why the asteroid is invisible to northern hemisphere observers until just before close approach: it is approaching from "underneath" our planet. On the other hand, after close approach it will be favorably placed for observers in the northern hemisphere. (NASA/JPL-Caltech)

An asteroid half  the size of a football field will come zipping past Earth at an almost uncomfortably close distance on Friday, and you can watch it online.

If you were hoping to just crane your neck skyward and watch the space rock fly by overhead, think again: Though NASA scientists say this is the first time in recorded history that an asteroid this large will fly this close to Earth,  it will still appear too small to see with the naked eye.

People in the Eastern Hemisphere may be able to spot the asteroid zoom by with the help of strong binoculars or a small telescope, but here in the Western Hemisphere, it will be nearly impossible to see it even with these visual aids because its closest approach will take place during daylight hours.

Asteroid flyby: Call off the space crew; no deep impact expected

You don’t have to miss the sky-watching fun, though. Thanks to the wonders of the Internet and live streaming video, there are several places where you can track the asteroid online.

NASA will provide a Ustream feed of the flyby from a telescope at the Marshall Space Flight Center in Alabama. The broadcast starts at 3 p.m. and goes until 6 p.m. PST on February 15. NASA researchers will also be on hand to answer questions that are tweeted in from the public.

Slooh.com will also be streaming live images from two observatories of the flyby accompanied by a real-time analysis and discussion from Slooh’s team of astronomers. The site will also create a moving image of the asteroid hurtling against the background of the stars. Slooh’s live stream also goes from 3  to 6 p.m. PST.

You can also check out streaming images from the Clay Center Observatory in Brookline, Mass., which will be pointing its space camera at the asteroid from 3 p.m to 1 a.m. PST. The images from this camera will be brought to you by a team of high-school students. You can access the video feed from the observatory’s Ustream channel.

At its closest approach, the asteroid known as 2012 DA14 will be just 17,200 miles from Earth, or about 1/10th the distance between the Earth and the moon.

At that distance the asteroid will be closer to us than some communication satellites, but NASA astronomers have said again and again that there is no chance that the asteroid will hit us.

So don’t worry, and enjoy the show!

    I'm Still Hiding Under My Bed!

    I like the way the picture shows it flying over what appears to be the north or south pole. So we don't have to worry if we are living in a populated area.

  3. scott says:

    If it is closer than satelites then it has a chance of hitting one, then it could deflect towards earth???

  4. rbrockman says:

    ahhhhhhhhhhhh….excuse me….but ahhh….sooner or later these will hit earth because of it double impact draw from the earth and moon gravitatiionals pulls both pulling apart, and together at certain times. Do we know when these certain times show up ??????

    • @Fellstorm says:

      Yeah we do. The actual trajectory that can carry an asteroid on a path that will eventually hit us is called a "keyhole" (named for the small size of the potential area of this space). If an asteroid's path takes it through this "keyhole" then we know it will hit Earth on its next go-round. If it misses this keyhole, then we're safe for another orbital cycle.

    Great Odin's Raven!

  6. Morton Thiokol says:

    Thanks to Clint Eastwood, Tommy Lee Jones, Donald Sutherland, James Garner, and the other space cowboys for deflecting the asteroid away from a collision course with earth!

  7. Sarah says:

    Are we gonna be able to see it in Texas?

  8. Peter Parkinson says:

    Not if it hits even in 2020 nobody is safe until it passes, it may force communications satellites etc back into the earths atmosphere near earth disrupting communications and the security of the planet, we rely in theses. We have 7 years to find away a of dealing with the large rock and finding ways to stop these potential rocks from hitting us.

    The real problem if hits with a force of an atom bomb then the residual fall out colatual damage may be a problem. This is an urgent problem we must procrastinate wold powers must deal with the problem NOW instead of sitting around hoping a praying it does not happen may on LA or NY London or Moscow.

  9. I wish we would have been able to send a probe to attach thrusters or something of that nature some passive plan for next time. or even just to slow it so we could capture and devour it. I don't know.
