It is very likely that a comet has hit the earth in the distant past. It is possible that a comet striking the earth led to the extinction of the dinosaur.
Yes, Mars & Jupiter have both been hit by comets.
Yes. They are really called asteroids. A few times they caused mass extinctions. For example this is what killed the dinosaurs.
Probably several times. It is assumed that a third of Earth water came from comets and it was a comet that hit the Earth 65 million years ago and caused the dinosaur extinction.
as far as i am aware it is haley's comet
yes
maybe...
A super comet is one that passes very closely to earths surface. It is said that if a super comet hit earth, it could wipe out existence as we know it.
yea and we will die
I don't think so
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!
We don't currently know when a comet will hit planet Earth.
No, a comet will NOT hit earth in 2012.
Halley's Comet
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
Probably several times. It is assumed that a third of Earth water came from comets and it was a comet that hit the Earth 65 million years ago and caused the dinosaur extinction.
