Having to do with the planet Uranus.

Uranian is a nineteenth century term that referred to a person of a third sex — originally, someone with "a female psyche in a male body" who is sexually attracted to men, and later extended to cover homosexual gender variant females, and a number of other sexual types. It is believed to be an English adaptation of the German word Urning, which was first published by activist Karl Heinrich Ulrichs in 1864 and 1865 in a series of five booklets which were collected under the title Forschungen über das Räthsel der mannmännlichen Liebe ("The Riddle of Man-Manly Love"). Ulrich developed his terminology before the first public use of the term "homosexual", which appeared in 1869 in a pamphlet published anomymously by Karl-Maria Kertbeny.
