We don't currently know when a comet will hit planet Earth.
Comet Lulin will not hit the Earth; it won't even come especially close.
No, a comet will NOT hit earth in 2012.
yes
Halley's comet is not predicted to hit Earth in the foreseeable future. The next time it will be visible from Earth is in 2061.
we cant survive a comet and besides they dont hit the earth
Depends on how big the Comet is.
lol it causes damage such as creating some crater,,,,,,,,,,,, it is very rare 4 a comet to hit earth lmao
it could be the end of the earth
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.
no they all died when a comet hit the earth.
it is believed that the earth had no livingisms until a comet hit the earth with orgamisms on it.
