Anasteroidas big as a refrigerator lately smashed intoEarth ’s atmosphere just hours after it was first discover by astronomers . It is the 5th time that investigator have spotted one of these cosmic rocks before it hit us .
The asteroid , named 2022 EB5 , was first detected by Krisztián Sárneczky , an uranologist at the Piszkéstető Mountain Station , part of Konkoly Observatory in Hungary , on March 11 . Two hour later , the outer space rock , which measured around 6.5 feet ( 2 meters ) across , slammed into Earth ’s atmosphere at an gauge speed of around 39,600 mph ( 63,700 km / h ) and most likely detonate , accord toEarthSky . Based on its f number , the rock and roll was around one - third of the length between the Earth and the Sun Myung Moon away when it was spotted .

After the asteroid ’s detection , NASA ’s " Scout " impact hazard assessment system began tracking the place rock . When it became clear that the asteroid would hit Earth , Scout automatically alerted the Center for Near Earth Object Studies ( CNEOS ) at NASA ’s Jet Propulsion Laboratory ( JPL ) in California . The CNEOS team predicted exactly where and when the asteroid would collide with , harmonize to a JPL statement .
" We were able-bodied to determine the potential impact locations , which ab initio extended from western Greenland to off the seacoast of Norway , " Davide Farnocchia , a navigation engineer at JPL who helped develop Scout , say in the statement . “ As more observatories tracked the asteroid , our calculations of its trajectory and shock emplacement became more precise . "
The asteroid hit Earth ’s atmosphere above Jan Mayen , an unpeopled volcanic island around 310 miles ( 500 kilometers ) east ofGreenlandand around 370 mile ( 595 km ) northeast of Iceland , at around 10:23 p.m. local time , just as promise , according to the affirmation .

witness in Iceland and Greenland reported run into a lustrous light in the sky and hearing a loud noise , consort to theNew York Post . Experts call up that they likely observed the asteroid as it became a fireballmeteor , according to EarthSky .
A bolide meteor is a case of extremely shining meteor that emits lightness equal to or with child than that of Venus in the night sky , grant to theAmerican Meteor Society ( AMS ) . This is due to clash between the meteor and Earth ’s atmosphere , which heats up the rock and releases energy in the form of light . If the fireball meteor also explode , it is called a bolide , and it can also make a transonic thunder , consort to AMS .
Even though our major planet is collide with with asteroids on a frequent groundwork , 2022 EB5 is only the fifth asteroid that has been spotted by uranologist before it clash with Earth ; the first - ever Earth - impactor was spot in 2008 .
" midget asteroids like 2022 EB5 are numerous , and they touch into the air quite often – approximately every 10 month or so , " Paul Chodas , director of CNEOS , said in the argument . " But very few of these asteroid have actually been detected in place and note extensively prior to touch on , basically because they are very faint until the last few hours . " Even then , a survey telescope has to pore on just the right part of the sky at the right time for one to be notice , he append .

However , we can catch one’s breath insure that any larger asteroids with hazardous impact potential difference would be spotted and tracked much sooner , similar to how the revelatory asteroid was spotted in the 2021 film " Do n’t depend Up . " Nevertheless , the arrival of 2022 EB5 provided a unique chance for the planetary defense community to test its potentiality and showed that we are well equipt to accurately track asteroids ’ trajectories , according to the argument .
