Abstract: The results of multifactor and orbital analyses of near-Earth Apollo-group asteroids (2013 WM, 2015 DU180, 2011 BT59, 2013 YC), which exhibit a genetic relationship with the April Chi-Librid meteor shower, are presented. The hypothesis that these asteroids are extinct fragments of a previously disintegrated cometary body has been confirmed.

Keywords: meteoroid shower, asteroid, extinct comet, near-Earth asteroids, orbital evolution, orbital resonances.
