Light-curve of Ryugu, folded with a synodic period of 7.63 h. The zeropoint is at 57581.0 MJD. 3D shape models of Ryugu were derived from Müller et al. (2017) for the mid-exposure time of spectral observations (color code corresponds to different solar insolations, with dark blue being the minimum and yellow being the maximum, in the range ~0−700 W/m2).
