14827 Hypnos magnitude of 18.65, while infrared radiometry gave a radar albedo of no more than 0.067 and a diameter of at least 740 meters. The "Collaborative Asteroid Lightcurve Link" assumes a standard optical albedo for carbonaceous asteroids 0.057 and derives a diameter of 907 meters with an absolute magnitude of 18.94. The diameter agrees with Tom Gehrels 1994-publication "Hazards due to Comets and Asteroids" in which he estimated a mean-diameter of 900 meters for "Hypnos". This minor planet was named after Hypnos from Greek mythology. He is the god of sleep, son of Nyx and Erebus and twin brother of Thanatos.
Hypnos feared to enter her realm. His wife, Pasithea, was one of the youngest of the Graces and was promised to him by Hera, who is the goddess of marriage and birth.
