Now we know just how powerful that issue was . According to unexampled dataposted by the NASA Jet Propulsion Laboratory ’s Center for Near Earth Object Studies andflagged by CNET , the object ’s hit with the atmosphere released the energy of around 1.4 kilotons ( 1,400 tons ) of TNT .
That may sound like a lot ( and it is ) . But such events are comparatively vulgar , just unremarkably give without much flash . Roughly 71 percent of the Earth ’s control surface is cover by water , and humankind arefar from every bit distributedover its estate , mean that many impacts go with few or no human eyewitnesses .
A number of impacts in 2018 top last week ’s , though as CNET observe , the explosion over Cuba was one of the more far-famed fireball since the meteor thathit Chelyabinsk , Russianear the Carry Amelia Moore Nation ’s border with Kazakhstan in 2013 . Scientists say that burst explode with the force ofover 470 kiloton of TNT , or virtually as strong as the MK-18 “ Ivy King ” in 1952 , the largestpure - fission turkey ever testedby the U.S. at 500 kilotons . accord to aTulane University fact sheet , the Chelyabinsk target was probably around 56 - 65 feet ( 17 - 20 meters ) in diameter .

The object that exploded over Cuba was belike much smaller , probably aroundthe size of a new wave . Cuban media reported that local come up what they believe was what remained of it after it burned up in the atmosphere in the form of diminished , black rocks around the size of a mobile phone . Onlyminor property damagesuch as shatter window — plausibly from thesonic boomgenerated by the target surpassing the speed of phone — was reported to have resulted , with no injuries .
