The 11 February event radiant point estimation using the registered and differenced NavCam images. The slower‐moving particles have begun to curve back toward Bennu under the influence of its gravity. If we assume that they travelled in straight lines and trace their paths backward (yellow vectors), the estimated radiant point (red cross) is off‐body, showing the biasing effect of the approximations that we made with respect to the independent OD solution of Leonard et al. (2020) (blue cross, on body).
