The International Astronomical Union (IAU) currently lists around 1200 meteor showers, raising questions about their reality given our current understanding of the Solar System, and the need for a comprehensive re-evaluation. This ongoing study aims to assess the feasibility of these showers originating from known near-Earth comets and asteroids, considering their orbital dynamics, dust production capabilities and residence times. Our study focuses on several key aspects:
- Impact Configurations from Near-Earth Comets: We estimate the number of possible meteor shower orbits produced by near-Earth comets, taking into account the Kozai and precession cycles.
- Active Asteroids as Parent Bodies: We examine active asteroids as potential sources of meteor showers, considering their quantity, dust production rates and lifetime expectancies.
- Near-Earth Asteroids Contribution: We explore the role of near-Earth asteroids in generating meteor showers.
By integrating these factors, we aim to determine if the current near-Earth environment can indeed support the existence of 1200 meteor showers. This work-in-progress seeks to align our understanding of meteor shower origins with the observed data. The findings will contribute to our broader comprehension of the dynamics and interactions within the near-Earth environment.
