Russia meteor's origin tracked down


www.bbc.co.uk said:

Astronomers have traced the origin of a meteor that injured about 1,000 people after breaking up over central Russia earlier this month.

Using amateur video footage, they were able to plot the meteor's trajectory through Earth's atmosphere and then reconstruct its orbit around the Sun.

Wow, that's impressive:

Quote

Dr Stephen Lowry, from the University of Kent, said the team had done well to publish so quickly.
"It certainly looks like it was a member of the Apollo class of asteroids," he told BBC News.
"Its elliptical, low inclination orbit, indicates a solar system origin, most likely from the asteroid belt between Mars and Jupiter.
Dr Lowry added: "Perhaps with more data, we can determine roughly where in the asteroid belt it come from."

Talk about good forensics.

You know I have about a dozen bookmarks for science news sources; I don't need them any more.  I just follow here.
