Standard Galactic Astrographic Documentation

Standard Galactic Astrographic Documentation (SGAD) was used by the InterGalactic Astrographical Society to scientifically denote s and their s. The system was usually prefixed by SGAD, denoting the documentation used, followed by the name of the object's parent or planet, followed by either a lowercase letter or a number. For example, the planet Lexicon, the third planet in around the star Dorumîs, would be denoted as "Dorumîs c." Any of its moons would be Lexicon/1, Lexicon/2, et cetera.
