History and specifics
- The FASA RPG source material lists this as a "mixed" population, making it unclear whether it is a colony world or the homeworld of a native inhabitation that also hosts populations of other Federation member races and cultures.
Castor's multiple system consists of six stars, including Castor B, which is orbited by Castus. The Castor system is visible from Earth in the Sol system, 49 light-years distant, as part of Human history's Gemini constellation. (TOS video game: 25th Anniversary; ST reference: Star Charts)
The Castor vicinity was in neutral space unclaimed by major governments by the 23rd century in the Kelvin timeline, with the only notable known nearby system being Protari. (ST video game: Fleet Command)
