Pollux

Pollux's position, three degrees past Castor

Pollux is Beta Geminorum, an orange giant of magnitude 1.1 and the brightest star in Gemini, though Bayer lettered it second. In the tropical zodiac it stood at 22°31′ Cancer in 1950, 23°13′ Cancer in 2000 and 23°34′ Cancer in 2025. Precession moves the equinox, the zero point of the zodiac, backwards through the stars, so each star appears to advance about 1° in 72 years. That is also why a star of the constellation Gemini sits in the tropical sign Cancer.

Using the standard 1° orb, a person born in 1950 has a planet on Pollux between 21°31′ and 23°31′ Cancer; a person born in 2025 needs one between 22°34′ and 24°34′. Castor, the other Twin, is about three degrees earlier, so the two stars are read separately.

Pollux lies 6.68° north of the ecliptic, close to the Sun's path, so the zodiac conjunction is a reliable guide. Ptolemy, in Tetrabiblos I.9, says the star in the head of the following Twin is like Mars.

The boxer who shared his immortality

Pollux, Polydeuces in Greek, was the son of Zeus and Leda and the twin of Castor, whose father was the mortal king Tyndareus. Pollux was the great boxer of Greek legend and fought for the Argonauts, defeating a king who challenged every stranger to a fight. Together the twins rode, fought and rescued their sister Helen.

When Castor was killed, Pollux, who could not die, asked Zeus to let him share his life with his brother. The twins were granted alternate days, one among the gods and one beneath the earth. The fighter's strength and the brother's sacrifice belong to the same star. Astrologers draw both into its meaning: combativeness and loyalty, the fist and the open hand.

Mars in the tradition

Ptolemy's Mars nature sets Pollux apart from Mercurial Castor. Medieval authors and Vivian Robson in 1923 described the star as spirited, bold and shrewd, linking it with boxing and physical contest, and also with rashness, cruelty and craftiness when it was afflicted. The tradition paired the two Twins as mind and fist.

Astrologers today read Pollux as a star of courage and competitive drive. The craftiness of the old texts becomes tactical sense, the boxer's ability to read an opponent. The myth adds something the tradition rarely stressed: loyalty strong enough to give up an advantage. People with a strong Pollux contact are often fiercely protective of family and friends and will step into a fight on their behalf.

In Cancer, the Moon's sign, the Martial energy turns toward kin and home. The fight is often for the family, the team or a close circle, and the risk is taking up battles that are not yours.

Pollux conjunct a planet

The Sun reaches Pollux around 14–15 July, so people born then carry a Sun on the star. Astrologers read it as a protective fighting spirit under a Cancer exterior: quietly tough, stubborn under pressure and loyal to the people close by.

The Moon on Pollux brings strong emotional reactions and a readiness to defend family. Feelings tend to come out as action. Learning when to hold back keeps that from turning into quarrels.

Mercury here gives a sharp, combative mind and skill in argument and strategy. Venus brings passion and loyalty in love, with jealousy as the risk. Mars on Pollux doubles the star's nature and gives physical courage, stamina and a love of competition; sport, martial arts and demanding physical work give it an outlet. Jupiter turns the fighting spirit toward causes and justice. Saturn adds endurance and patience, the long training before the bout. Uranus, Neptune and Pluto mark a generation's style of struggle more than a person's.

Pollux on the Ascendant or Midheaven

Pollux rising gives a firm, ready manner, someone who looks capable of handling a confrontation. People may come to you for protection or expect you to take a stand. The tradition's warning of rashness belongs here, and pausing before reacting is the useful habit.

On the Midheaven the star favours a reputation earned through courage and competition. Careers in sport, defence, emergency work, advocacy or any field that rewards nerve suit it. The myth adds a quieter possibility: recognition for loyalty and for sharing success with those who helped win it.
