Lauretta, Heterogeneous mass distribution of the rubble-pile asteroid (101955) Bennu. Sci. Adv. 6, eabc3350 (2020).<br><br>It includes the Bennu shape model used to perform our analysis in *.obj format, consisting of vertices and face definitions. <br>It includes a Matlab file giving the spacecraft-derived gravity field for asteroid Bennu. This file was created by the OSIRIS-REx Radio Science Working Group Team, based on analysis performed at the Jet Propulsion Laboratory. In addition to the gravity field coefficients, the file also contains the associated covariance and other data related to the gravity field solution.
