The Barringer crater in Arizona has quite a record of an even closer approach...

It seems to me I recall that the meteor that caused that crater was 90 feet in diameter. This one was slightly larger. Though I don't know why they are calling it an asteroid. Asteroids start at several kilometers in diameter, do they not?

Well, I just checked. Looks like Meteor Crater was caused by a nickel-iron meteor 150 feet in diameter traveling 40,000 mph. That would make it a lot bigger and faster than the one that will be missing us tomorrow.

I do not think that they change to the meteor terminology unless an astroid hits the atmosphere.

Then it becomes a meteor or meterorite if it survives.
