We Almost Died!
by Steve Gibson, Sep 01, 2000 5:40am PDTIn case you thought those asteroids hitting the Earth movies things werent realistic, just last week a half-mile wide asteroid wizzed by the Earth just missing us (about 12times the distance from us than our moon). Of course if it were coming any closer, we would have sent up a oil drill team and blew that sucker up! (Thanks my pov)
Asteroid 2000 QW7 falls into a category of Near-Earth Objects (NEOs) called Potentially Hazardous Asteroids, or PHAs. [snip] Gravitational nudges by Earth, Mars or Jupiter can potentially set such asteroids on a collision course with our planet, says Yeomans.

The only thing that saved that movie was Liv Tyler and her mountainous body in the animal cracker scene.
I don't remember anything else in that movie.

However, a suitably large object *may* be deflected by the earth's gravitational field - this is sometimes referred to as the "slingshot effect" - the same principle used to increase the speed of our space probes.
Of course, if the object was headed on a direct course for Earth, and it's speed was sufficiently fast relative to Earth, Earth's meager gravity wouldn't do much but draw the object in.
Hope you don't live near the coast...
