Pollux

POL-uhks

greek: Πολυδεύκης (Polydeukes)

Definition

Pollux is a first-magnitude orange-giant star at the head of the celestial Twin Pollux in Gemini (its formal name is Beta Geminorum). At about magnitude 1.14 it is slightly brighter than its companion Castor. Today it sits at about 23 degrees Cancer along the zodiac, adjusted for precession — classical observers placed it within Gemini. In Greek myth Pollux (Polydeukes) is the immortal twin of the Dioscuri, son of Leda and Zeus, paired with the mortal Castor.

In Tradition

In the Western fixed-star tradition (Robson 1923, public domain; Brady), Pollux is read as the Mars-natured twin — courage, physical strength, daring, athletic gift — achievement that comes from inborn power rather than learned skill. The shadow side is rashness, cruelty, or the misuse of those natural gifts. The myth of Pollux trading half his immortality with Castor adds a theme of sacrifice. Pollux pairs with Castor as the canonical fixed-star twin, the two carrying readings that complement each other yet stay distinct.

In Practice

Astrologers working with fixed stars count Pollux as active when a natal planet or angle conjoins its current position along the zodiac within roughly one degree, or when it is paran-related to a personal point. The traditional reading welcomes Pollux on the Ascendant or with Mars for physical courage, an athletic calling, or martial work that succeeds through inborn boldness. A chart in which both twin stars touch personal points carries the twin theme more strongly — and modern fixed-star practice usually reads Castor and Pollux together when both touch natal points.

Historical Origin

Greek attestation: Hesiod; Pindar's *Nemean* 10 (the Dioscuri); Aratus' *Phaenomena* 146-147. The Hellenistic reception is in Ptolemy's *Tetrabiblos* I.9 (the Twins). Robson (1923, public domain) assigns Pollux a Mars nature; Brady's *Brady's Book of Fixed Stars* is the modern reference. The IAU's 1928 boundaries place the star within Gemini, even though precession has carried its zodiac position into early Cancer.

Etymology

Origin: Greek. Meaning: From Greek Polydeukes, one of the Dioscuri, the immortal twin born to Leda and Zeus.
