This series of four photos captures the asteroid that came about 41,000 miles from us Monday - less than 2x the distance of the usual man-made satellite, and much closer than the Moon. What was even scarier than this near miss? No one in the mainstream media seemed to notice until last night. I hope *someone* was paying attention. . .

Update: via the NYT Lede blog, an animation of 2009 DD25, our asteroid friend with no respect for personal space:
And an explanation of who exactly watches out for 2009 DD25 and its ilk:
Mr. Revkin also explained that the federal government does, in fact, pay scientists at the Jet Propulsion Laboratory, run by NASA in Pasadena, Calif., to keep a look out for big rocks heading our way. But a decade after Hollywood's "Armageddon" briefly made their work seem urgent, it turns out that money is tight around the lab's Near-Earth Object Program. Last July, even before the possibility of the economy cratering was first mentioned, Mr. Revkin wrote that "budget constraints" had "slowed NASA's efforts to meet its goal of identifying 90 percent" of the very largest chunks of rock hurtling about the solar system.
Mr. Revkin added that "rocks similar in size to the one that exploded over Siberia," and the one that passed us by on Monday, are "probably a long way down," on NASA's list of priorities.(source)

That gif is great! I've been wondering why this is such quiet story.
I'd think that it's a photo worth 6 billion sighs of relief.
What woulda happened if the fucker smashed into the Earth?
It woulda looked something like this:

But the music wouldn't be nearly as good.

Check out Phil Plait's book Death From The Skies . It has a great chapter on asteroid collisions.
Speaking of which, jackd on bad astronomy commented on that .
He links to the impact effects calculator, where you can figure that stuff out for yourself.
A small asteroid did hit the Earth last October: 2008 TC3. See here for an image of the aftermath.
You rock!
