Procyon
Authors: IAU-WGSN Etymology Group, Susanne M Hoffmann, Youla Azkarrula
The name originates from Greek "pro kyon", "before the dog". Historically, the Latin translation "Antecanis" was occasionally used. Today, this term is used as a star name in the constellation Canis Minor but in antiquity, it designated the area – originally likely a single-star asterism.
Etymology and History
The bright star Procyon was possibly used in Mesopotamia as an indicator for the rising of Cancer. The stars in Cancer are so faint that you can barely see them at dusk – but the bright Procyon rises at the same time, which is suitable for telling the time.
Spelling Variants:
- Prokyon (Greek), Procyon (Latinized Greek),

Var. 1 (Περὶ τοῦ Προκυνóς): This is the constellation that precedes Canis Major. It is known as Orion’s Dog. It is said, in fact, that it was placed beside Orion because of the dog’s passion for hunting. The fact is that the Hare can be seen very close to it, along with other animals at its side.
Var. 2 (Προκυνóς): This is the dog that precedes the Great Dog, and it is called “Procyon” (Pre-Dog) because it comes before the Dog. It is Orion’s dog. Indeed, it is said that it was placed beside Orion because of his passion for hunting. The fact is that the Hare can be seen very close to it, and other animals by its side.
Procyon has three stars, one of which, the first [to rise], is bright. It bears a resemblance to the Dog, hence its name Procyon; moreover, it rises and sets before the Great Dog.
