Uranus (mythology) castrated Uranus, from Uranus' blood, which splattered onto the earth, came the Erinyes (Furies), the Giants, and the Meliae. Also, according to the "Theogony", Cronus threw the severed genitals into the sea, around which "a white foam spread" and "grew" into the goddess Aphrodite, although according to Homer, Aphrodite was the daughter of Zeus and Dione. In the Olympian creation myth, as Hesiod tells it in the "Theogony", Uranus came every night to cover the earth and mate with Gaia, but he hated the children she bore him. Hesiod named their first six sons and six daughters the Titans, the
Climate of Uranus radiates hardly any excess heat at all. The total power radiated by Uranus in the far infrared (i.e. heat) part of the spectrum is times the solar energy absorbed in its atmosphere. In fact, Uranus's heat flux is only W/m², which is lower than the internal heat flux of Earth of about 0.075 W/m². The lowest temperature recorded in Uranus's tropopause is 49 K (−224 °C), making Uranus the coldest planet in the Solar System, colder than Neptune. Another hypothesis states that when Uranus was "knocked over" by the supermassive impactor which caused its extreme axial tilt, the event also
