The First Instrumentally Documented Fall of an Iron Meteorite: atmospheric trajectory and ground impact

Jarmo Moilanen, Maria Gritsevich, Jaakko Visuri

Iron meteorite falls are rare compared to stony meteorites, and until recently no iron meteorite had a reliably determined pre-atmospheric orbit. This changed on 2020 November 7, w…

Distance-Independent Atmospheric Refraction Correction for Accurate Retrieval of Fireball Trajectories

Jaakko Visuri, Maria Gritsevich, Janne Sievinen

Accurate determination of fireball direction is essential for retrieving trajectories and velocities. Errors in these measurements have significant implications, affecting the calc…

Oort cloud perturbations as a source of hyperbolic Earth impactors

Eloy Peña-Asensio, Jaakko Visuri, Josep M. Trigo-Rodríguez +4

The observation of interstellar objects 1I/'Oumuamua and 2I/Borisov suggests the existence of a larger population of smaller projectiles that impact our planet with unbound orbits.…
