    The Rate of Falls of Meteorites and Bolides

    We perform a statistical analysis of 926 confirmed falls of meteorites that occurred in the period 1860 to 2017. The distribution of meteorites over masses is approximated with a lognormal law. It has been sho...

    Frequency of meteorite falls

    Between 10,000 and 100,000 tons of space matter falls to Earth annually [1]. Given that seven billion people now live on Earth, that means each resident of the planet could potentially find about 8 g of space ...
