    More from Spaceweather....close asteroid approach, right now..

    Space Weather News for Jan. 25, 2009
    http://spaceweather.com

    CURIOUS ASTEROID FLYBY: Newly-discovered asteroid 2009 BD is slowly passing by Earth today only 400,000 miles away. The approximately 10 meter-wide space rock poses no significant threat, but it merits attention anyway: The orbit of 2009 BD appears to be almost identical to the orbit of Earth. 2009 BD may be a rare "co-orbital asteroid," circling the sun in near-tandem with our planet. If current measurements of the asteroid's orbit are correct, 2009 BD will remain in Earth's neighborhood for many months and possibly years to come. Visit http://spaceweather.com to view the asteroid's curious orbit.

    SOLAR ECLIPSE WEBCASTS: At the time this email is being sent, an annular solar eclipse is just hours away. In support of the 2009 International Year of Astronomy, astronomers in the eclipse-zone have set up a network of cameras stretching from South Africa to Indonesia. Live webcasts will begin around 0600 UT on Monday, Jan. 26th. Follow the links at http://spaceweather.com .

    Meh, not even remotely extinction-event class. That little piece of crap would probably burn up in the atmosphere.

    Come on, universe, show us what you got! BRING IT ON!

    Is it really small enough to burn up in the atmosphere? What is the largest size that would burn up? What is the smallest size that would get through and do heavy damage?

    Well, Meteor Crater in AZ was about a 30 meter rock hitting. A 10 meter rock would likely just explode in the upper atmosphere.

    Dear gods of luck,

    Please restrict your clever and ironic retribution to x136 alone. Perhaps have a tree fall on him or something? The rest of us are most thankful that you have kindly not thrown a large rock at us recently to teach us a valuable lesson.

    Doesn't the burn-up potential depend on the speed, angle of entry, and composition of the meteor?

    As in, one 10 meter object burns while the other punches a hole in the earth?

    No need for anything illegal, Pcad, and I didn't say it was going to hit....it should be naked eye visible, though, or with a good pair of Binocs. I just thought it was pretty cool is all, considering Astronomy is one of my little hobbies.

    See, I actually have some curiosity about things in the Universe OTHER than jacking up my post count.

    I think it was around 1908? Leveled trees for 1,000's of hectares.
