Resulting rotational characteristics of meteoroids ejected from the 2P/Encke comet for meteoroid sizes D 1 mm, 1 cm, and 10 cm, three ejection models (see Sect. 3.2), and two types of gas-meteoroid interactions (D means diffuse and S specular reflection of gas molecules from the meteoroid’s surface).
