Arrival : What's the name of that movie from 20-odd years ago…

felt like a documentary, about these 3 asteroids about to hit Earth at strategic points.

We decide to shoot them, the final scene is 100 more incoming

It's really bothering me!

Is is one of these? I hope you figure it out, because it sounds excellent.

Thank you mge1108!
It was a made-for-TV CBS movie called "Without Warning" : http://www.imdb.com/board/10111735/

Your hint about "Asteroid" led me to another message board where I found it
