As of Wednesday ( Feb. 19 ) afternoon , NASA decreased the likeliness of asteroid 2024 YR4 hitting Earth in 2032from 3.1 % to 1.5 % .
The probability that a majorasteroid , heavy enough to pass over out an integral city , will hit Earth in 2032 has just increase to 1 in 32 , or 3.1 % , according toNASA .
Asteroid 2024 YR4 has a 1 in 32 chance of hitting Earth at the time of writing.
On Feb. 7 , NASAincreased the likelihoodthat asteroid 2024 YR4 will hit Earth in seven years time from 1.2 % to 2.3 % . The odds of encroachment then climbed to 2.6 % , and are now at 3.1 % , according to thelatest dataon NASA ’s Center for Near Earth Object Studies website .
Asteroid 2024 YR4 has an approximate diameter of around 177 feet ( 54 meters ) , or about as wide as the tend tower of Pisa is marvellous . But while it is too small to finish human culture , the asteroid could stillwipe out a major city , release about 8 megaton of energy upon impact — more than 500 times the energy released by the atomic bomb that destroyedHiroshima , Japan .
The good news program is that there ’s still a 96.9 % probability that the asteroid will omit Earth entirely , and as researchers learn more about its flight , the betting odds of a strike are likely to decrease to 0 % , based on its current risk grade in the NASA data point . There ’s also a tiny 0.3 % chance that YR4will tally the mooninstead of Earth , Live Science antecedently cover .

Scientists expend a measure called theTorino Scaleto categorize the risk posed by nearby asteroid and comets . With a Torino Scale valuation of 3 out of 10 , YR4 is capable of localized destruction and passes the 1 % wallop chance verge ( meaning the danger of a potential impact is estimated to be greater than 1 % ) .

Additional notice will give scientist a more accurate estimate of the asteroid ’s scope , which usually means they ’ll be more sure-footed it wo n’t hit Earth . Many other objects on NASA ’s asteroid danger list have ended up with an impingement chance of 0 % after more datum became uncommitted .
A team of scientists was recentlygranted emergency useof theJames Webb Space Telescope , the most knock-down place telescope , to analyse YR4 in the coming months and value its risk , as well as its true size .
YR4 is currently the only known large asteroid with a more than 1 % hazard of strike Earth , according toNASA ’s world-wide defence blog . In the unconvincing event that YR4 does collide with Earth , it would probably hit somewhere along a " danger corridor " load across the easterly Pacific Ocean , northerly South America , the Atlantic Ocean , Africa , the Arabian Sea , and South Asia , accord toNASA .
