Shapes and orientations of each formed moon after 3 h of simulation time after a sub-escape-velocity merger between the two moonlets in Table 2. The value α, represents the counter-clockwise rotation relative to the initial position of moonlet A in Fig. 1 around its barycentre. The particles originally belonging to moonlet A have been coloured in blue, while the corresponding particles from moonlet B are orange. The black arrow in each plot is pointing in the direction of the primary.
