There are 360 degrees on our orbit, so there is a 1 in 360 chance that sooner or later that thing is going to intersect our orbit. It is a crap shoot alright. But it is not the only object out there that is poised to ring our chime.

anything who's orbit crosses ours....crosses our orbit twice... just like that asteroid did with the moons orbit, it will do the same with ours.

since everything is weightless in outer space, can the moon be used as a shield?:confused:

Seems to me, and I may be wrong, but the moon is kept in place by the Earth's gravity. If an object the size of this asteroid hits it, it may throw it out of orbit. If the moon spins out of orbit, what would it do to the Earth? There is a certain amount of tension there. Would the Earth be jolted out of its orbit too? Not sure if anyone has calculated that possibility.

i forgot about the gravity thingy.
i guess if god defecates onto the earth, we're pretty much screwed.8O

Hardly. The Moon has a diameter of about 5000 km, which means that in just its diameter it is over 12,000 times the size of the asteroid. It would be like expecting a mosquito to move an elephant for the asteroid to have any effect on the Moon.

A mouse can move an elephant.

Try hitting a bird when driving on the highway. It has an impact (pun intended) on the car.

Not a chance with something the size of this asteroid. Both earth and the moon have been hit by bigger without any effect on our orbits.

If something threw the moon or the earth out of orbit-well, game over for all of us.

I did say a mosquito. And in fact that comparison may have exaggerated the mass of the asteroid.

That said, the asteroid menace is a strong argument for further exploration of space and an increase in funding to the world's various space programs.
