Webwith the Ortiz et al. (2006)andThirouin et al. (2010) rotational lightcurves. These results already seem to indicate that Orcus’ rotation is not tidally locked to its satellite, but because the satellite orbital period is much longer than the usual observing windows for ro-tational variability studies, the question arises as to whether the WebAlso, its short term variability was studied in Ortiz et al. who found a likely rotation period of 10.08 hr (although periods at around 7 hr and 17 hr were also possible). Later, Thirouin et al. included more data, obtaining a rotation period of 10.47 hr.
