A mammoth " potentially hazardous " asteroid that may be twice the size of the Empire State Building is prepare to zoom past Earth Thursday ( April 28),according to NASA .
Theasteroid , name 418135 ( 2008 AG33 ) , has an estimated diameter between 1,150 and 2,560 understructure ( 350 to 780 meters ) and will break into Earth ’s orbit at a blister 23,300 mph ( 37,400 km / h ) . Thankfully , the asteroid is expected to skitter past our planet without any risk of exposure of impingement .
This artistic concept image shows an asteroid flying by Earth.
At its penny-pinching point , the asteroid — move around at more than 30 times the speed of sound — will add up within about 2 million mil ( 3.2 million kilometer ) ofEarth , which is just about eight times the mediocre distance between ground and themoon . This may sound like a big break , but by cosmic standards , it ’s actually a stone ’s cam stroke away .
come to : We may finally know why spinning - top asteroid Ryugu has such a weird form
NASAflags any space object that descend within 120 million nautical mile ( 193 million km ) of Earth as a " near - ground object " and any fast - moving target within 4.65 million air mile ( 7.5 million km ) as " potentially hazardous . " Once the objects are flagged , stargazer closely monitor them , look for any diversion from their predicted trajectory that could put them on a collision course with Earth .
— Why are asteroids and comets such eldritch shapes?—How many satellites orbit Earth?—Is Earth flourish or shrink ?
The incoming space rock was first discover on Jan. 12 , 2008 , by asteroid surveyors at the Mt. Lemmon SkyCenter lookout station in Arizona and last zipped past Earth on March 1 , 2015 , according to NASA ’s Center for Near Earth Object Studies ( CNEOS ) . The asteroid swings by our planet roughly every seven years , with the next airless flyby predict to hail on May 25 , 2029 .
Thursday ’s asteroid might not even be the magnanimous blank space rock to hurtle past us in the coming weeks . That deed of conveyance will in all probability go to 467460 ( 2006 JF42 ) , which has an count on diam between 1,247 and 2,822 foot ( 380 to 860 m ) and will be travel at roughly 25,300 mph ( 40,700 km / h ) when it return us on May 9 , 2022 .
If stargazer ever do spy an asteroid flying flat at Earth , place agencies around the macrocosm are already work out on ways to possibly deflect the object . On Nov. 24 , 2021 , NASA plunge a ballistic capsule as a part of its Double Asteroid Redirection Test mission , which design to redirect a nonhazardous asteroid by ramming it off course , Live Science antecedently describe . Chinais also in the early planning stages of an asteroid - redirect mission . By slamming 23 Long March 5 rockets into the asteroid Bennu , the country suppose it would be able to divert the space rock from apotentially catastrophic impact with Earth , Live Science antecedently reported .
