The Sun joins Castor on July 12

Fixed star Castor, Alpha Geminorum, is a complex multiple-star system located in the head of the Northern Twin of Gemini Constellation. Combined magnitude 1.58, spectral type A1.

Castor is designated α, but it is actually fainter than β Geminorum (Pollux). Although Castor appears to the naked eye as a single star, it is a multiple-star system made up of six individual stars (sextuple star system). All three visual components – Castor A, Castor B and Castor C – are spectroscopic binaries, pairs of stars locked in tight orbits.

Castor A is composed of a white star and a red dwarf companion. Castor B also consists of a white star and a red dwarf. Castor C consists of two red dwarf stars believed to have identical properties. ^[1]

Star	Magnitude	Spectra
Castor A	1.93	A1V + dM1e
Castor B	2.97	Am + dM1e
Castor C	9.83	dM1e + dM1e

Castor and Pollux were the Two Gods of Sparta in Greece, sons of Leda, Queen of Sparta. Their Roman equivalents are Apollo and Hercules. Pollux (Hercules) comes from the Greek Polydeuces, hence he was the Boxer. Pollux was the immortal twin and a skilled Horseman. When Castor was killed in battle, Pollux asked his father Zeus (Jupiter) that he die to forever be with Castor. Zeus killed Pollux with a bolt of lightning and placed the twins in heaven as the constellation Gemini.

Castor Astrology

Fixed star Castor has the spectral type A1, indicating the planetary nature of Venus.

CASTOR. α Geminorium. A binary star, bright white and pale white, situated on the head of the Northern Twin. It represents Castor, the mortal one of the twins, famous for his skill in taming and managing horses. Sometimes called Apollo, and symbolically named A Ruler yet to Come. According to Ptolemy it is of the nature of Mercury; to Wilson, Simmonite and Pearce, of Mars, Venus and Saturn; and, to Alvidas, of the Moon, Mars and Uranus. It gives distinction, a keen intellect, success in law and many travels, fondness for horses, sudden fame and honor but often followed by loss of fortune and disgrace, sickness, trouble and great affliction. Its natives are said to be mischievous and prone to violence. ^[2]

CASTOR. α Geminorium. A complex system of stars, and all revolve around a common center once every 380 years. The main star has a spectral characteristic of A2 and the companion has a spectral class of AO. Each of the stars has an invisible companion and in reality this is a sextuple system. It is a bluish-white system. Of yore they were a portent of violence and mischief. They produce sudden rises and honors, followed by a fall, failures, gains, losses, troubles, afflictions; keen intellect, disappointments, fortunes, restrictions, turbulence, imprisonment. ^[3]

Castor is one of the Twins and Pollux the other. While Castor has a Venusian nature (according to its spectral type) and Pollux a nature as that of Mars, Castor has always been considered to portend mischief and violence while Pollux eminenece and renown. This, of course, is due to the fact that the energy of Mars can be extremely valuable in such areas as war and business and politics, while Venus can cause an indiolent character leading to his own destruction. The other, and opposite, indications of these stars include for Castor a keen mind and many travels, and for Pollux a cruel, rash nature and a propensity to be connected with poisons. ^[4]

Castor (Apollo), Alpha Geminorum. Castor, in the Twins and together with Pollux, is called “Thiassis eyes”, a name given to these two stars by the ancient Germans. The Babylonians considered both stars as a pair belonging together, as “herdsman and warrior”. The Phoenicians recognized in the twin stars, helpers if in peril on voyages at sea. Castor is influenced by Mercury and has a blend of Jupiter in it. Linked with the Moon and Mercury, it has the effect of such people being blessed with a good nature and fine morals. It is also supposed to convey refined manners. A conjunction with the Sun or Mars will make for energetic characteristics and a certain tendency for satire and cynicism, depending on the position of Mercury or Mars in the chart as a whole. ^[5]

Castor, α Gemorium, was the horseman of the twins, just as Abel was the animal keeper, and he shared Abel’s fate of being killed by his brother. Pollux got his brother drunk to make the task easier, or as one wag among classical astrologers put it: He got Castor oiled! In astrology, Castor is counted a star of misfortune, and the specific association with breaking an arm or leg may come from the Ptolemaic classification of this as a Mercury star; a planet which is much associated with the arms, or the limbs generally. Castor is also noted in natal astrology for proneness to nervous breakdowns, and the author has often found it prominent on the horoscopes of his many clients in neurotic distress. But Castor’s Mercury quality does have a better side to it, as does all else counted ‘bad’ in this world of the heavens. People with it prominent and well-aspected are exceptionally gifted intellectually, a good creative quality along with this – a bonus from the combination of intellectual Gemini Constellation and intuitive Cancer Sign. Where these potential geniuses often need help is in not letting their concern for others go ‘over the top’ beyond their own sensible state of responsibility and practical ability to help, the negative qualities of the combined Gemini-Cancer qualities. Castor’s connection with Mercury goes deeper yet. The Greeks knew it at one time as Apollo, and, at another time, they called the planet Mercury by that name. Still earlier, Apollo was that other sun which we have since called Phaeton, which is no more. And just as that was Sun’s close companion then, so is Mercury its closest one now. And to cap that, Castor, the former Apollo, is in fact a Binary Pair of stars, as once were Sun and Phaeton. A binary pair evokes a deep-seated fear in humanity, an unconscious recall of The Disaster, so that we tend to react to it just as one does all the wrong things in a moment of crisis, if it happens to half-awaken in one some earlier trauma of the same kind. The author has experimented with acquainting ‘Castor-stricken’ clients with the true story behind our fear of binaries, and the results so far in banishing panic reactions in crises have been very heartening. ^[6]

Constellation Gemini

Ptolemy makes the following observations; the stars in the feet of Gemini have an influence similar to that of Mercury, and moderately to that of Venus; the bright stars in the thighs are like Saturn. It is said to cause trouble and disgrace, sickness, loss of fortune, affliction and danger to the knees. By the Cabalists it is associated with the Hebrew letter Qoph and the 19th Tarot Trump, The Sun”. ^[2]

Astrologers assigned to this constellation guardianship over human hands, arms, and shoulders; while Albumasar held that it portended intense devotion, genius, largeness of mind, goodness, and liberality. Considered the House of Mercury and a fortunate sign. Chinese astrologers asserted that if this constellation were invaded by Mars, war and a poor harvest would ensue. ^[8]

Mercury conjunct Castor: Remarkable psychic powers entailing criticism and ridicule but eventual prominence. ^[2]

Natives with a well-aspected Mercury will have psychic ability, however, if Mercury is adversely aspected to Neptune, this psychic ability can create confusion in particular with a negative or no Moon aspect, and there is the possibility of turbulence. Such natives might appear normal but are plagued with internal dissension. Prominence is possible. ^[3]

There are no extreme problems at this point except that the energy flow to the parathyroids may cause an imbalance in the digestive fluids; that is, an imbalance of fluids at times, and at other times, a little less. This is not particularly severe. When the digestive enzymes are abundant, they can eat heavier foods. When low, they should eat lighter foods. Lettuce is excellent for this point. These are the persons who can write articles or books but success through their writings would not come during their lifetime. Recognition would come after the person has left the earth plane. Only then will they get the recognition and praise they deserve for helping humanity. ^[7]

Venus conjunct Castor: Strange and peculiar life, many extreme ups and downs, unfavorable for marriage. ^[2]

These natives have the ability to overcome adversity, and generally such natives lead a life that is out of the ordinary. This conjunction is not particularly good for marriage unless the marriage partner is of a congenial nature. The more negative nativities can experience many or problems, martial, violence, even chronic, difficult-to-diagnose or serious illness possible. ^[3]

This causes the natives to be overly parental in relationships, whether they are business, family, friendships or their marriage partner. They are continually attempting to mother everyone, making sure they are all wearing warm clothes in cold weather or have some hot soup to eat. This is extremely overdone, but it is not really harmful. It can become overbearing, however. ^[7]

Mars conjunct Castor: Evil disposition, much travel, aimless life, many ups and downs. ^[2]

These natives will have it made, success seems to come to them, when for some reason conditions change. The kind of changes can be many, illness, marital problems, even legal matters, regardless of what causes the conditions, such natives will find their life altered, some might even become almost ‘basket’ cases, and their life style will go into another direction. The more strong-willed will make a comeback, in time. Violent conditions also possible under this conjunction. ^[3]
