In the wee forenoon hour on Sunday ( Jan. 21 ) , a midget asteroid come hurtling through the sky and smash into Earth ’s atm near Berlin , get a bright but harmless fireball visible for miles around . Such sighting typically occur a few times a year — but this one was singular because it was first discover by scientist roughly three hours before impact — only the eighth time that researcher have spotted one of these blank tilt before it hit .
The asteroid , dubbed2024 BXI , was first disclose by ego - proclaim asteroid hunterKrisztián Sárneczky , an uranologist at the Piszkéstető Mountain Station , part of Konkoly Observatory in Hungary . He place the cosmic rock using the60 - atomic number 96 Schmidt telescope at the observatory . curtly after the blank rock ’s breakthrough , NASAgave a elaborated prediction of where and when the meteor would strike .
" Heads Up : A midget asteroid will disintegrate as a harmless fireball west of Berlin near Nennhausen shortly at 1:32am CET . Overseers will see it if it ’s clear!“NASA tweetedon the night of Jan. 20 .
live camerain the city of Leipzig in northern Germany caught footage of the exceptionally bright meteor , watching it seem and disappear in the dyad of a few seconds . The asteroid , which measured an approximate 3.3 feet ( 1 meter ) across-the-board before shock , in all probability started to decompose around 30 mi ( 50 kilometers ) west of Berlin and " probably throw off some meteorite on the background " along the way , Denis Vida , a postdoctoral associate in meteor physics at Western University in Canada , state CBS News .
Sárneczky has fall upon hundreds of asteroid in recent old age , and was thefirst to detect asteroid 2022 EB5around two hours before it slam into Earth ’s air . He used Konkoly Observatory datum to spot that incoming tilt , too .

His sighting is incredibly unusual . According to theEuropean Space Agency , 99 % of near - Earth asteroids smaller than 98 foot ( 30 metre ) acrosshave not yet been discovered . The smaller an asteroid is , the closer it must be to Earth before scientist can detect it , which can make it difficult to forecast impacts in cash advance , experts say .
In some case , near - Earth asteroid canhide in the glare of the Sunday , such as themeteor that scud out from the direction of the rising sunover the city of Chelyabinsk , Russia , in 2013 . That surprise space tilt shattered windows , temporarily blind pedestrian , inflicted instant ultraviolet Robert Burns and injured more than 1,600 people .

politics outer space agencies are presently developing Modern technology to scan the skies for asteroids before they make impinging with Earth , include NASA’sNEO Surveyor orbiter , currently planned to launch in 2027 , and ESA’sNEOMIR , which is n’t expected to launch until after 2030 . Starting in 2025 , theVera C. Rubin Observatoryin Chile — funded by the National Science Foundation — will catalog thesolar systemfrom the ground , and is expected to greatly help asteroid - hunt efforts .
" It took us 200 geezerhood to discover all the asteroids we know to escort , about 1.2 million asteroids,“Mario Jurić , the Rubin Observatory ’s solar arrangement discovery team lead-in and the music director of the University of Washington ’s DiRAC Institute , told Astronomy . " In the first three to six months of Rubin , we will double that . "
