Actual collisions are pretty rare. Most 'space debris' burns up in the atmosphere long before it hits the planet.
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.
There is only one way that a comet or asteroid can affect the earth. These two things can affect the earth if they enter the earth's atmosphere and hit our planet.
Fortunately not very often - because if one does hit, it would be a major catastrophe.
It is possible for comets and asteroids to hit Earth, but they are extremely rare events.
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. Asteroids can hit anywhere on earth.
No, a comet will NOT hit earth in 2012.
they would of found out about asteroids because when the dinosaurs were extinct a massive comet hit earth and it destroyed it and the reason planet earth was created again was because a large enough rock formed into a planet and if the rock is not large enough then it wont form into a planet
yes
make big holes in the earth!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
