SSG-1 alpha-3

SSG-1 alpha-3 codes are 3-letter planetary codes published by the Central Government of the Solar System to represent planets, moons, dwarf planets, and other celestial bodies of interest. They are most prominently used for the Internet's 3-letter TLDs. They are also used as postal codes when appropriate for the interplanetary postal system for paper mail. They were released in their first edition in 1984.
