Can a comet/asteroid hit the earth?

Question

i need help with this

Answer 1

Yes, and it's happened in the past.

250,000,000 years ago, and again 65,000,000 years ago, two separate objects impacted te Earth's surface, resulting in E.L.E.s (Extinction Level Event(s)).

It can also happen again - NASA tracks Apollo objects, among others, that come as close as the orbit of the moon.

Answer 2

I was watching the Jay Leno show late night and he had some guy on their who worked for NASA. He was extremely intelligent, since he was an astrophysic or something like that. He was on the show stating that their is an asteroid heading in the earth's direction and that there was a 1 in 45,000 chance it will hit earth. He projected that this asteroid will be in the area around 2036. This was one of jay leno's guest and I think he was considered to be the worlds smartest man also.

Answer 3

the wear and tear and longterm result it has relies upon on its length and speed of the effect. maximum asteroids that hit earth pass at hundreds of miles an hour. no count if that's some hundred ft lengthy it might desire to easily reason close by injury and impression the region around the effect. working example, as asteroid the size of a house might have the quantity of tension equivalent to the bomb that hit Hiroshima, pulling down and destroying each thing in the encompassing radius. notwithstanding it if it a mile extensive or extra advantageous it might desire to reason a lengthy term impression on earth. via the time you upward push as much as a mile-extensive asteroid, you're working in the a million million megaton variety. This asteroid has the potential this is 10 million cases extra advantageous than the bomb that fell on Hiroshima. this is able to flatten each thing for a hundred to 2 hundred miles out from floor 0. In different words, if a mile-extensive asteroid have been to right away hit large apple city, the stress of the effect in all probability might thoroughly flatten each ingredient from Washington D.C. to Boston, and can reason extensive injury according to risk a million,000 miles out -- this is as a procedures away as Chicago. the quantity of airborne dirt and dust and particles thrown up into the ambience might block out the sunlight and reason maximum residing issues in the worldwide to perish. If an asteroid that extensive have been to land in the sea, it might reason large tidal waves hundreds of ft severe that would desire to thoroughly scrub the coastlines in the location. it does not only impression the location however the entire earth. The shockwave from the effect might shuttle in the time of the earth and reason earthquakes on the different factor. The particles thrown out into area might fall returned to earth and reason meteor showers around the realm. the lengthy term results of one of those asteroid may well be devastating. it might replace the climate of the earth, inflicting a short lived ice age (variety of like a nuclear wintry climate) and convey many animal and plant species to extinction or on the edge. The earth will ultimately have the flexibility to climb out of this hollow (or crater) like it did with the dinosaurs yet not devoid of a few large ameliorations occurring. In different words, if an asteroid strikes Earth, it is going to likely be a very, fairly undesirable day no count how large that's. If the asteroid is a mile in diameter, this is in all probability to wipe out a large number of existence in the worldwide. enable's desire that doesn't ensue every time quickly!

Answer 4

Yes It has even been postulated that the earth would look like the surface of the moon were it not for the active surface of earth which erodes most craters away over the years.

Answer 5

Yes. There are thousands of craters on the Earth's surface where we have been struck.

There was a relatively destructive impact in about 1908 in Tunguska, in Siberia.

Answer 6

Yes at anytime!

It already happened in the past. But scientists are trying to prevent it from happening again.

Answer 7

Yes there are craters in the earth.

Answer 8

Yes, they can. They have in the past, and there are lots of possibilities for impacts in the future.

Answer 9

Yes...there is a BIG crater in Arizona.

Answer 10

Yes, but I wouldn't worry about it unless it hits you.
