The headlines should all have been about 2009 DD45.

The BBC reports that on Monday a previously untracked asteroid passed within the distance of the moon's orbit that was large enough to cause an explosion of 1000 atomic bombs on impact.

Re-read that sentence a few times and see where your imagination leads you.

Such an event has happened in the recent past in Siberia, 1908, fortunately it was a mostly uninhabited area.

This really should have grabbed more headlines, and must now concentrate minds.

Think - where were you on Monday afternoon and how different your day could easily have been.2009 DD45 intersects Earth's orbit just as Earth is passing. A close shave gromit. (H/T to JPL Small-Body Database Browser here ).
