Title: Meteoroid to hit Earth in a few hours
Post by Tony on 10/06/08 at 13:40:57

It's being reported in the minor planet mailing list that Sudan will be hit tommorow by an object not large enough to cause any damage.  But this may be the first instance of an impact being predicted at all.

This image was generated with Gravity Simulator, using data from JPL Horizons and http://www.cfa.harvard.edu/mpec/K08/K08T50.html.  It shows an impact at 02:48:12 with the bolide colliding with Earth at a speed of 12.851 km/s.

Photos from space of the entry of the asteroid in the earth's atmosphere obtained by the satellite Meteosat-8:

That picture is amazing.  I'm disappointed that we don't have any photos or video from the ground.

Thanks for the image, and welcome to the forum, Mazda!

Thanks Tony !

It really is a pity that the entry of this asteroid has not been photographed on the ground despite the fact that the first confirmations of the asteroid's entry came from a few lucky eyewitnesses.

However recently the site APOD published a beautiful image of another Fireball (photographed by other lucky observers) that can illustrate how the entry of 2008 TC3 looks like:

Well, maybe in another opportunity we become the lucky observers.
