COMPLEXES OF MINOR BODIES IN THE SOLAR-SYSTEM

A search for parent bodies for 22 short-period meteoroid streams with an account of long-period planetary perturbations was carried out. Five minor body complexes are found among short-period comets, Earth-crossing asteroids and meteoroid streams. There are ten members in the major complex: two comets - P/Schwassmann - Wachmann 3 and P/Pons - Winnecke; four asteroids - 1984 KD (3671), 4788 PL, 1987 SJ3, 1987 PA; and four meteor showers - Sigma Leonids, Alpha Bootids, Tau Herculids and June Bootids. The results of numerical simulation of orbital evolution for three short-period comets are presented.
