Earth rolls dice with Asteroids

There is more of this to come.

Study the orbital graphic in the NASA article.

Two issues:
1. If you throw at the same instance a handful of little rubber jax balls along the rim of a descending cone, they'll separate into different descending orbits, although they were all same source (the parallel is DA--14). So how can NASA say, "They [the orbits of DA-14 and R-M) are not even close." Relative to the size of this universe, I'd say they're damned close and could have been same source, like the jax balls; but I only am inclined to that belief because their arrival time was so insanely closely calibrated! What are the odds?
2. NASA actually says of the R-M orbit: " The other blue ellipse, stretching way beyond the orbit of Mars, is the first determination of the orbit of the Russian meteor." WOW! NASA is admitting this is only "...THE FIRST DETERMINATION..." of R-M's orbit. Yet they claim total knowledge: How Do We Know...[the two orbits]...Aren't Related?"
Hmmmmmmmmm

anything COTA says! BTW, COTA, my husband and I could not get your Panic Sex button to work (right after the R-M impact news), so we put on our Roswell Grey beanies and improvised.
Is it still down?
