(DW: The Curse of the Black Spot) It had at least five planets: Sirius Alpha (BFA/BBCR: Max Warp), Androzani Major and Minor (DW: The Caves of Androzani), Sirius IV (DW: Frontier in Space) and Sirius V (DW: City of Death).

History
Sirius (known as The Dog Star) was used as a guide-point for navigation on Earth for much of its early history. It was only later found to consist of two stars.

In the 17th century, Sirius was still used for navigation in sailing. When Captain Henry Avery obtained a spaceship, one of his trips was to see Sirius. (DW: The Curse of the Black Spot)

By the time of the Earth Empire, the Sirius system had been colonised by humans, though by 2540 Sirius IV was an independent dominion planet. (DW: Frontier in Space) The corporation Sirius Conglomerate was a major power in the system. (DW: The Caves of Androzani)
