Share Scientists from the Ural Federal University, the University of Helsinki and the Finnish Institute for Geospatial Research have developed and successfully tested the world’s first model that accurately locates meteorites and all their fragments on the Earth’s surface. Thus, it is possible to establish the final mass of cosmic matter on our planet. An article about the model was published in the Monthly Notices of the Royal Astronomical Society. The novel model can be used to revise the flux of extra-terrestrial matter onto the Earth, as it provides a possibility of estimating the terminal mass of meteorite fragments reaching the ground.
