I have been wondering, though, for a while, “What would the effect be if a large meteor/small asteroid missed the earth by a mile (at its point of nearest approach, it was one mile above the ground)?”

There would be, of course, a heck of a sonic boom; over water it would probably trigger a tsunami, over a built-up area it would probably be as bad as being nuked.

The parts that burned off would probably have the same sun-obscuring effect as a volcanic eruption.

What else?

Depending upon the makeup of the object itself, there could be ill effects from the smoke or smaller fragments breaking off. The notion of meteorites being toxic isn’t entirely a creation of comic books and science fiction.

Your scenario borders on the impossible. Any object that got that deep into the troposphere (5,280 ft up) would be unable to maintain escape velocity (25,000 mph) in all likelihood it would either explode (due to atmospheric friction and pressure) or be captured by Earths' gravity (hit the dirt).

However assuming the impossible the effects of such a fly by would depend on the composition of the meteor. The "sonic boom" of a mile wide object traveling 60,000 mph one mile overhead would be very impressive, lol. Sadly it is above my pay grade to do the math on that. Fluid Dynamics is not my thing.
