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.
Greek mythology in popular culture bodies have been named after elements of Greek mythology. The constellation of Scorpius represents the scorpion that attacked Hercules and the scorpions that frighted the horses when Phaëton was driving the sun-chariot; while Capricorn may represent Pan in a myth that tells of his escape from Typhon by jumping into the water while turning into an animal - the half in the water turned into a fish and the other half turned into a goat. 1108 Demeter, a main-belt asteroid discovered by Karl Reinmuth on May 31, 1929, is named after the Greek goddess of fruitful soil and agriculture.
