Analysis of a bright flash in Jupiter’s atmosphere observed by an amateur astronomer in August 2019 has revealed that the likely cause was a small asteroid with a density typical of stony-iron meteors. The impact is estimated to have released energy equivalent to an explosion of 240 kilotons of TNT—around half the energy released in the 2013 Chelyabinsk event at Earth. The results have been presented today at the EPSC-DPS Joint Meeting 2019 in Geneva.
