Whew! That Was Close, Another Near Miss

On March 23, 1989, Asclepius, a mountain size asteroid barely missed the planet Earth. It would have been the equivalent of 40 Hiroshimas and had worldwide catastrophic effects, if it collided with the planet. These occurrences happen more frequently than you would think, but happen less often than an asteroid genre movie hitting the local cineplex. National Near Miss Day is March 23rd each year.

Which of these select movies with significant plot points about near misses or collisions by astronomical objects or bodies with the planet Earth is your favorite one?
