// How the math works
NASA Standard Breakup Model
Fragment count follows N(Lc) = 6·M0.75·Lc−1.6 where M is the mass of the smaller object (kg) and Lc is the minimum fragment characteristic length (m). Kinetic energy KE = ½μv² uses the reduced mass μ = m₁m₂/(m₁+m₂). The specific energy E* = KE/M_total determines whether a collision is catastrophic (E* > 40 kJ/kg) or cratering.
