Abstract: Among numerous characteristics of planets, atmosphere is one of the most essential property to determine the planetary habitability.Recent advances in observational techniques have enabled not only the detection of planets in outer solar systems, referred to exoplanets, but also measurements of its atmosphere.Consequently, the origin and formation history of planetary atmosphere have became a central topic in planetary science closely linked to potential for life beyond Earth.Meteoroid accretion is a fundamental and ubiquitous process in planetary systems, and it can substantially alter planetary atmosphere.The abundant lunar-craters indicates that the early Earth had also been exposed to numerous meteoroid events.A meteoroid gravitationally accelerated by a planet generally has a high velocity and drives rapid chemical-reactions, including the synthesis of organic species.
