what is the chance of an asteroid hitting the earth?

Question

Thanks

Answer 1

I found this data on-line a while ago, can't remember from where, but I know it's fairly accurate.

Size: less than 50 meters across
Interval: less than 1 every year
Consequences: most don't reach the surface, rather they disintegrate in Earth's upper atmosphere

Size: 75 m
Interval: once every 1000 years
Consequences: Iron meteorites make craters like Meteor Crater in Arizona; Stony meteorites produce airbursts like Tunguska; land impacts destroy area the size of a city

Size: 160 m
Interval: once every 5000 years
Consequences: Irons, stones hit ground; comets produce airbursts; land impacts destroy area size of large urban area (New York City, Tokyo)

Size: 350 m
Interval: once every 15,000 years
Consequences: Land impacts destroy area size of small state; ocean impact produces mild tsunamis

Size: 700 m
Interval: once every 63,000 years
Consequences: Land impacts destroy area size of moderate state (Virginia); ocean impact makes big tsunamis

Size: 1700 m (over one mile)
Interval: once every 250,000 years
Consequences: Land impact raises dust with global implications; destroys area size of large state (California, France)

Answer 2

The chances are very small, but far from nonexistent. There are far too many asteroids that could impact Earth for us to currently keep track of. For example, one passed within 210,000 km of us but wasn't detected until TWO DAYS LATER!

Right now, an asteroid known as 2004 VD17 has the best chance of hitting us on May 4, 2102---a 1 in 4,000 chance. As the object's orbit is more precisely determined, that 1 in 4,000 chance will probably go up considerably.

The bottom line is that we know of no objects that will strike Earth, but there's always the chance of one sneaking in undetected.

Answer 3

A good question. Believe it or not, you're about as likely to be killed by an asteroid impact as in a plane crash, if you live in a developed country and travel by plane sometimes. Asteroid impacts are much less common than plane crashes but they kill more people. If a big one hit, it would kill us all. But the one that killed the dinosaurs happened 65 million years ago, so there's only about 1 chance in a million that another like that will happen in your lifetime.

Answer 4

Nothing to worry about if you are a Christian and believe the Bible. The Scripture do not prophesies the end of time as because of a comet nor asteroid striking mother Earth. Nuke war yes. Luv

Answer 5

One hundred per cent, if you wait long enough. In the last 200 million years alone, there have been over 80 strikes which have left craters of 1 kilometre diameter or more. Half of them are over 10 kilometres diameter, which would have had pretty drastic effects on the biosphere for quite a number of years.

Answer 6

100% - asteroids hit earth every day... an asteroid large enough to cause widespread extinction will hit the earth about once every 100 million years or so....

Answer 7

that's actual frightening. Yeah, I heard approximately that a pair years in the past, yet, as maximum anybody is companies to do, i did not think of of it as something larger, although, now that I proceed to exist it, isn't one considerable concept of dinosaur's distruction an asteroid collission? i could maximum probable be dwelling in 2029, and a million/60 probability is surprisingly freaky. yet, there may be greater effectual tachnology (probable not, nevertheless) by utilising then and with a bit of luck it must be prevented. although, one quite frightening ingredient is something I observed on the historic past Channel or Discovery (i don't undergo in innovations) approximately 4-5 years in the past. It become with regard to the ancients Mayans or Aztecs (a kind of civilizations), and that they have got been explaining how the civilization's time recording become quite precise. Like, the Mayans (i'm optimistic iit become them, so i bypass to seek advice from them) predicited whilst some style of comet could bypass Earth hundreds of years interior the destiny, and scientists on the instant comprehend that they have got been in basic terms approximately quite a few hours (or so) off from the truthfully time. besides, the Mayans additionally had different predictions, and a exceptional form of of them have been shown again genuine or on the brink of genuine. yet, one such predicition (alongside with the teach, a prior instructor of mine additionally instructed me this as quickly as, and he's extensive on those styles of issues) become whilst the Earth is going to be destroyed, and it become predicted around the 2030s (if I undergo in innovations wisely); i know, the Mayans had very progressed arithmetic and astonomy, supposedly. i don't know how plenty to believe, yet whilst a number of their predicitions have been shown to become genuine, then?... Plus, there are all of the main amazing religions that concentration on the apocolypse and stuff, so, yeah, surprisingly frightening stuff. besides, I probable have been given way off subject count, even though it quite is exciting. As for the truthfully asteroid hitting Earth in 2029, that's actual frightening, yet i'm gonna be a physically powerful, worry-unfastened human and worry with regard to the themes of NOW. Lolz... now and then, the Gibbler P.S. wish i did not scare absolutely everyone...

Answer 8

The probability is 1, or 100 percent. It is a matter of when it will happen and the answer is "Probably not tomorrow or next year."

Answer 9

Either 0% or 100%. We just don't know which.

Answer 10

One chance out of infinity.
