Abstract—

This study is focused on the relationships between the κ-Cygnid meteor shower and different groups of asteroids crossing the Earth’s orbit (the so-called near-Earth objects (NEOs)). The analysis is based on the visible structure of the meteor shower and a comprehensive strategy for estimating the proximity of orbits of two bodies. The κ-Cygnid meteor shower (abbreviated as KCG) is observed from August 3 to August 25 every year; it is classified as a minor shower, and the size of its mean orbit is around 3.2 AU, while the geocentric velocity is 20.9 km/s. No parent body (PB) of the shower has been found among comets so far. Relationships between the shower and asteroids, as potential PBs of the shower, are under active examination; some hypotheses on this subject can be found on the website of the Meteor Data Center (MDC) of the International Astronomical Union (IAU).

κcycyid流星雨及其与近地小行星的关系

摘要-

这项研究的重点是κcygnid流星雨与穿越地球轨道的不同小行星群之间的关系(所谓的近地天体(NEOs))。该分析基于流星雨的可见结构和用于估计两个天体轨道接近度的综合策略。每年8月3日至8月25日观测到κ天鹅座流星雨(缩写为KCG)。它被归类为小阵雨,其平均轨道大小约为3.2 AU,而地心速度为20.9 km / s。到目前为止,尚未在彗星中找到淋浴的母体(PB)。淋浴和小行星之间的关系,作为淋浴的潜在PB,正在积极研究中;
