Hard. If you want more specific than that, you're going to need to know about the mass and speed of the comet.
Depends on how big the Comet is.
We don't currently know when a comet will hit planet Earth.
No, a comet will NOT hit earth in 2012.
Jupiter. Jupiter was hit in 1994 by a comet called Shoemaker Levy9.
Worn timing chain?
Comet Lulin will not hit the Earth; it won't even come especially close.
we cant survive a comet and besides they dont hit the earth
it depends on the size of the comet if it was small it would do about 5o/ out of a 1000 on earth if it was a very big one it would do about 989/ out of a 1000 so it depends on size
yes
If a comet hit the Earth hard enough and went through the core, the whole Earth could fall apart.
