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.

Post-perihelion UVES spectra of interstellar comet 3I/ATLAS reveal elevated NiI and FeI production explained by direct sublimation of Ni(CO)4 and Fe(CO)5 from subsurface layers, with a transient heat source accounting for the pre-perihelion Ni excess.
Simulations of hypervelocity rocky-on-icy impacts show porosity controls crater morphology but not the efficient vaporization of the rocky impactor material.
