Figure 1.

Reconstructed particle trajectories from the 11 February event. The trajectories (in green) range from ballistic or suborbital, which reimpact within a few hours, to hyperbolic, leaving the Bennu environment completely within a few hours. Particle events occur in the late afternoon (local solar time), gaining velocity from Bennu's rotation as they move toward the nightside of the asteroid. The red, green, and blue axes correspond to the x, y, and z axes (respectively) of the Bennu Sun Anti‐Angular Momentum (SAM) frame (Williams et al., 2018).
