In 1997 Tisiphone was studied by Worman and Christianson at the Feder Observatory located near [[Minnesota State University, Moorhead]], with the goal of determining its rotational peroid. A peroid of 8.824 ± 0.009 was arrived at, with the [[lightcurve]] data showing two distinct maxima and minima in its rotation.<ref name=ccd-photometry/> In 2001 Lagerkvist ''et al.'' published their results on a study of the Cybele asteroid family, which includes 466 Tisiphone.
