Genetic analysis of parameters of near earth asteroids for determining parent bodies of meteoroid streams

摘要

The present paper is focusing on determining genetic connections between small bodies of the Solar system and their parent bodies (PB) on the basis of analysis of Near Earth Asteroids (NEAs) parameters. In order to search for parent bodies of meteoroid streams, the asteroid groups, including Atira, Apollo, Amor and Aten, have been investigated. Currently, it is considered that surface of asteroids with elongated orbit is exposed to temperature fall: in perihelion it is heated and in aphelion it is cooled. At small orbital periods around the Sun (about 2-4 years) this may lead to formation of meteoroid clusters. On the basis of comparative analysis of orbit, size and chemical and mineralogical composition of NEAs, it is found that asteroids from Apollo group are most likely to be parent bodies of the studied meteoroid streams.
