"Hypnos" is an assumed carbonaceous C-type asteroid. As of 2018, no rotational lightcurve of "Hypnos" has been obtained from photometric observations. The asteroids rotation period and spin axis remains unknown. It has a low brightness amplitude of 0.05 magnitude which indicates that the body has a rather spheroidal shape. According to the NEOSurvey carried out by NASA's Spitzer Space Telescope, "Hypnos" measures 520 meters in diameter and its surface has an albedo of 0.22 based on an absolute
