A new three-point inverse solution using the α-β model reconstructs meteoroid masses and bulk densities from limited fireball observations, achieving 88% convergence on the EN catalog and producing a continuous density range of 300-4000 kg m^{-3} instead of discrete PE categories.

Dynamical simulations show mm-sized meteoroids impacting Earth below 17 km/s are mostly asteroidal if released in the last 150-200 kyr, with cometary fraction rising above that speed and dominating above 27 km/s.

Consistency between dynamical modeling and photometrically derived masses of fireballs

The Dynamical Origin of Millimetre-Sized Sporadic Meteoroids
Dynamical simulations show mm-sized meteoroids impacting Earth below 17 km/s are mostly asteroidal if released in the last 150-200 kyr, with cometary fraction rising above that speed and dominating above 27 km/s.
