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.
Libya (mythology) Libya (mythology) Libya (from ) is the daughter of Epaphus, King of Egypt, in both Greek and Roman mythology. She personified the land of Ancient Libya in North Africa, from which the name of modern-day Libya originated. In Greek mythology, Libya, like Ethiopia or Scythia was one of the mythic outlands that encircled the familiar Greek world of the Hellenes and their "foreign" neighbors. Personified as an individual, Libya was the daughter of Epaphus—King of Egypt, and the son of Zeus and Io—and Memphis. Libya was ravished by the god Poseidon to whom she bore twin sons, Belus and Agenor.
