Aerodynamic pressure distribution for Geminids (upper part) and asteroidal fireballs (lower part). Numbers and colors designate the actual aerodynamic pressure of fragmentation in MPa; the fractions represent the destroyed mass. The size of the pie chart is proportional to the size of the meteoroids assuming a spherical shape and ρ_bulk = 2500 kg m³ for Geminids and ρ_bulk = 3500 kg m³ for the asteroidal fireballs. See Table 1 for identification of Geminids and Table 2 for identification of the asteroidal fireballs.
