How dangerous would a very near miss by a large asteroid be?

Specifically, one that passes inside of earth's atmosphere but doesn't impact the ground?  How about a very shallow glancing blow?

If it doesn't hit the ground but just brushes the upper atmosphere, there's no danger except to satellites/astronauts.

If you mean a glancing blow on the ground, there's no such thing. If a large asteroid (say, 1 km) touches the ground it will be a gigantic explosion.
