Keane and Ermakov1 question the methods used in my earlier study2 to reveal true polar wander (TPW) of Ceres. I argue that their assessment of the methods used2 is ineffective as it lacks important robustness checks and presents serious biases, and that their arguments are not sufficient to support their conclusions.
