DR. ASTRO WAS WRONG and COTA WAS CORRECT! Asteroid DA-14 and Chelyabinsk ARE SAME SOURCE: Both APOLLO CLASS!

Well Hubba Hubba! Look at this article, quoting NASA/JPL NEOP's Paul Chodas and colleague!! That in fact DA-14 and the Russian asteroid were both Apollo Class but that DA-14's pass on Feb. 15, 2013 degraded its orbit to Aten Class!!! This vindicates COTA's original claim that DA-14 was inbound with debris!!
[link to en.wikipedia.org]
"The close approach to Earth reduced the orbital period of 2012 DA14 from 368 days to 317 days,[2][12] and perturbed it from the Apollo class to the Aten class of near-Earth asteroids.[2]"
See NASA's Chodas cited in footnote [2] above at bottom of linked article.
Turns out DA-14 was Apollo Class just like the Russian meteor, so that was wholly disinformation about the two being totally unrelated. Put that in Dr. Astro's pipe and watch his eyes glaze over! Both DA-14 and the Chelyabinsk monster (now recalculated as weighing 700,000 tons!) were Apollo Class asteroids!
You were right, COTA! Those behemoths flew in on the same day because they were traveling together temporally because THEY WERE SAME SOURCE!

Read COTA's original thread re: cited UK news article that Russian asteroid was APOLLO CLASS!
"Researchers plot the path of the Russian meteor and say it probably came from asteroid belt between Mars and Jupiter

"Astronomers have calculated the origin of a meteor that injured 1,000 people after breaking up over central Russia.

"They used amateur video footage to plot the path of the space rock that burned up over the city of Chelyabinsk causing shockwaves that blew out windows.

The results suggest the meteor belongs to a well known family of space rocks known as the Apollo asteroids, and probably came from an asteroid belt between Mars and Jupiter."
