Procyon in fiction

As one of the brightest stars in the night sky, Procyon (Alpha Canis Minoris in the constellation Canis Minor) regularly appears in science fiction.

[edit] Literature

In the Viagens Interplanetarias stories of L. Sprague de Camp its system contains the inhabited planets of Osiris, Isis, and Thoth.
The human colony world of We Made It (which is mentioned in Larry Niven's stories and books of the Known Space) orbits Procyon. Pierson's Puppeteers are said to have evolved in a solar system with a star similar to Procyon (which later became a red giant).
In Uller Uprising by H. Beam Piper, Procyon is the name of a contragravity warship equipped with rockets and autocannon of 40mm and 90mm calibers. It is instrumental in crushing the 'Geek Rebellion' of native, anti-human Ullerans.
In the Terran Trade Authority, Procyon is orbited by three planets, the middle of which, Sisuphos, is a barely-habitable mining world.

In the book Star Trek: Star Charts, Procyon is said to be the primary star system for Andoria, though this is a conjecture unsupported by onscreen evidence in any Star Trek series or film. According to Star Trek: Enterprise, the star was the scene of a formidable Federation victory during a war against an alien species known as the Sphere Builders. The USS Enterprise-J took part in this battle. In 2153, Captain Jonathan Archer was brought 400 years forward in time to witness part of the battle.

In Star Control II: The Ur-Quan Masters, Procyon is the primary star for the homeworld of the crystalline Chenjesu race, but during the game's events it is learned that the Chenjesu have fused with the Mmrnmhrm to become the Chmmr, effectively replacing the Chenjesu. However, it has nothing in common with the real star.
