Directions of ejection velocities in the ecliptical coordinate system. The origin of the coordinate system coincides with fragment 0, which is also the parent body of the cluster. The black dots with numbers represent the ejection velocity directions of the fragments belonging to the nominal cluster (the size of the dot corresponds to the fragment size) and the black cross in the center of the plot is the mean ejection direction. The gray color is used to show the ejection velocity directions of the cluster clones. For a better view, only 1000 clones are displayed. The triangle shows the position of the Sun. The flux of the small meteoroids’ incident on the parent meteoroid is shown by the color scale. This flux was determined using NASA’s Meteoroid Engineering Model 3 (Moorhead et al. 2020).
