Oh? You weren’t concerned? Never mind.
Apparently, last week the Minor Planet Center was just about to release an emergency warning that a large, extra-terrestrial body was just about to pass a hair’s breadth from the earth – it should have skimmed by about 3,500 miles away. That’s creepily close, when we’re dealing with space.
Fortunately (for our stress centers, I guess) a clever Russian scientist actually took the time to look at the nearly earth-bound mass, and to track its trajectory, and realized that it was, in fact, the European, comet-chasing probe, Rosetta. Rosetta is about the size of a utility van (with wings), and we are quite safe from it.
So, thanks to one plucky Russian astronomer, the world is safe again. You all still have a pretty good chance of getting hit by cars tomorrow, though, or by dead birds falling from the sky. Or of choking on something you thought would be harmless, like pudding.
