In 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.
