That’s about 1/6th of a mile wide.
An asteroid just half a mile wide wiped out the dinosaurs
These things are much more prevalant than we thought. There was just a recent photo of a new impact on the moon (last month) and also on Mars (sometime since last year) and remember Shoemaker-Levy left earth-sized holes in Jupiter.
But at least NASA is getting some important “muslim outreach” work done...
Well put! One quibble, the Chicxulub bolide was about six miles across, but a half-mile object would destroy civilization. This one is about 64 times bigger (in volume) than the Tunguska object, which flattened hundreds of square miles and left no apparent crater.
