Ellipticity values of our model asteroids plotted against the fraction of mass shed in each tidal disruption outcome. Seventy‐nine S‐class, 40 B‐class, and 76 M‐class disruptions are shown. The starting ellipticity for our model rubble pile is ﹩\epsilon _{\mathrm{rem}\,}=0.43﹩. Geographos’s ellipticity is ﹩\epsilon _{\mathrm{rem}\,}=0.64﹩. Note that most M‐class disruptions produce high ellipticities.
