Identifying parent bodies of meteorites among near-Earth asteroids

Abstract Meteorites provide an important source of information about the formation and composition asteroids, because level accuracy studies analyses performed in a laboratory cannot be achieved by any ground or space based observation. To better understand what asteroid types meteorite represents, it is crucial to identify body they originated from. In this paper, we aim determine possible parent bodies for known falls among population near-Earth asteroids (NEAs). By using similarity criterion DN, on geocentric quantities, found 20 NEA-meteorite pairs. performing additional numerical simulations backward dynamics, that 12 these pairs may associated with separation event from progenitor NEA, while remaining 8 appear ambiguous random associations. The most interesting are Pribram Neuschwanstein meteorites, which dynamically (482488) 2012 SW20 common age dating back 20−30 kyr ago, Motopi Pan meteorite, has three candidate bodies: (454100) 2013 BO73, 2017 MC3, 2009 FZ4. average time between our list appears 10 kyr, consistent expected collision frequency small NEAs. Based results, suggest 25 per cent meteorites do not originate main belt, but mainly little events happening NEAs inner Solar System.
