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.
It is too difficult to tell. There is no existing average for the velocity of comets, as all comets are different. Gravitional, solar and initial velocity have a lot to due with the velocity of a comet. Even though there is a great deal of variation, the answer would have to be very, very fast. Fast, that is, compared to earth standards. If a comet were to hit earth, for example, chances are that we wouldn't see or even know that it had hit. It would just hit. Not to scare you. The chances of a comet hitting the earth are slim to none.
we cant survive a comet and besides they dont hit the earth
A comet is a small solar system body that orbits the Sun. When close enough to the Sun, a comet exhibits a visible coma (fuzzy "atmosphere"), and sometimes a tail, both because of the effects of solar radiation upon the comet's nucleus . Comet nuclei are themselves loose collections of ice, dust and small rocky particles, ranging from a few kilometers to tens of kilometers across. So no Mars doesn't have a comet it does have a moon tho.
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
