Sirius is a binary star system consisting of two white stars orbiting each other with a separation of about 20 AU (roughly the distance between the Sun and Uranus) and a period of 50.1 years.- Old Coast, New Coast: Victoria, British Columbia (hakaimagazine.com)
Ever since the Hudson’s Bay Company selected this sheltered bay for its fur-trading fort in 1842, Victoria Harbour, in what is now Victoria, British Columbia, has been a gathering point. Crowds once assembled to eagerly check out the single women arriving from the United Kingdom on “bride ships” in the 1860s; to greet the Victoria-based fleet of North Pacific sealing schooners, the workhorses of the fur-seal industry that peaked in the 1890s; or to say farewell to troops departing for the two world wars.

Sirius is the brightest star in the night sky. Its name is derived from the Greek word Σείριος (Latin script: Seirios), meaning lit. ‘glowing’ or ‘scorching’. The star is designated α Canis Majoris, Latinized to Alpha Canis Majoris, and abbreviated α CMa or Alpha CMa. With a visual apparent magnitude of −1.46, Sirius is almost twice as bright as Canopus, the next brightest star. Sirius is a binary star consisting of a main-sequence star of spectral type A0 or A1, termed Sirius A, and a faint white dwarf companion of spectral type DA2, termed Sirius B. The distance between the two varies between 8.2 and 31.5 astronomical units as they orbit every 50 years.
