I thought Mytran was the one, but I didn't have the time to research it, so, he got demoted to "some". Sorry, buddy. Since both star systems have the family name "Canaris", they could be part a binary or multiple star system. For a real life example, we have the tertiary Alpha Centauri star system next door with stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. Internet queries say that perhaps up to 85% of all stars are in binary systems with some in triple or even higher-multiple systems. One article said that we have observed star systems with six stars. Switching to another show, Firefly's "Verse" has multiple stars. Maybe this can explain the high number of Rigil planets referenced throughout Trek lore. Another article says that Rigel is around 800 light years from Earth and is the brightest star in the constellation of Orion. Rigel is actually a three star system consisting of the blue supergiant Rigel A and two distant and much dimmer companions.
