No history or specifics are established for this location in Starfleet Command III, as its name was arbitrarily selected for a Federation system on the game map by the game software, with random attributes.
StarTrek.com claims there are "at least" six planets in the system.
Alpha Tauri A is an orange giant while Alpha Tauri B is a red dwarf. Alpha Tauri B orbits the primary at a distance of 97.5 billion kilometres. A reflective trail of mineral and ice debris can be seen trailing behind Alpha Tauri B as it travels along its orbit.
