Eventually, yes. It is inevitable. Overall, though, large impacts are very rare so it is unlikely that it will happen in our lifetime.
Yes. The surface of Mars is littered with craters from such impacts. In fact, every planet in the solar system has been hit by a comet... not just once, but many, many times!
No. Halley's comet is about 5 by 10 miles wide. Mars is about 4200 miles wide.
Venus is a planet, not a comet, so it does not have a tail.
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.
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
Martian meteorites were ejected from the surface of Mars during massive asteroid and comet impacts.
yes
Depends on how big the Comet is.
There is no record of a comet directly hitting Earth in recorded history. Comets are typically small icy bodies that mostly burn up upon entering the Earth's atmosphere due to friction with the air. However, they can cause spectacular meteor showers when their debris interacts with Earth's atmosphere.
