This one is up to 1600ft in diameter — nearly a third of a mile — if it hit on land, it would end our civilization.
The Meteor Crater object was about 100 yards across (about one-fifth in three dimensions, or less than 1/125th the size of something 1500 ft in diameter) and dug a hole a quarter mile deep and over 3/4 mile wide, plus ignited everything flammable for probably dozens of miles, knocking down everything else.
You know, they say we are tracking these for early warning, but in the last two years there have been quite a few, surprise this is something we didn’t see events.
While I understand the distances, the number of oops seems high.
