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.

Solar image analysis shows typical astrometric jitter of 0.342 μas pc from activity, below the ~3 μas Earth-planet signal at 1 pc, so stellar contamination does not prevent Earth-like exoplanet astrometry around Sun-like stars.
N-body simulations of main-belt asteroidal dust yield fluxes at inner planets that match scaled Grün and Müller models after calibration, with low-eccentricity grains dominating flux and high-eccentricity grains driving the high-velocity impact tail.
The 2023 February 27 fireball observed with ALIS_4D has a trajectory and orbit consistent with an Apollo-family asteroid parent body, with a computed strewn field along the Kiruna-Gällivare border in northern Sweden.
