Asteroids are used in astrology in a similar way to the planets. Asteroids are planetoids that orbit the Sun between Mars and Jupiter, and are not to be confused with Centaurs or Trans-Neptunian Objects. The asteroids are relatively new to astrology, having only been discovered in the 1800s. However, some of them (especially the largest of them), are believed by some astrologers to influence human affairs. Still though, they are often ignored within mainstream systems of astrology, especially in more traditional astrology systems like Vedic astrology or Hellenistic astrology. Their use has become significant to a few Western astrologers yet still only a minority of astrologers use the asteroids in chart interpretation.
The Former Planets
, Pallas Athene
(in order of chronology) were counted as planets between 1808-1845, when the smaller asteroids began to be discovered. Astronomically the status of Ceres has changed again. In a proposed Resolution in 2006, it was suggested as one of the 12 planets in our Solar System, but in the end was re-classified as a dwarf planet by the International Astronomical Union. Many astrologers believe that astronomical labels don't hold much weight in their practice as through history man's definitions and labels have changed, but the astrological significations of what are considered "astrological planets" (including the Sun, Moon and for modern astronomer Pluto) have not changed.
Ceres was the first asteroid discovered and is the largest asteroid of all, taking up about 1/3 of the entire mass of the asteroid belt . In astrology, to get an understanding of the nature of a planet the astrologers analyze the name given to it. In mythology Ceres was the Roman equivalent of the Greek goddess Demeter
. She was the goddess of agriculture & when her daughter Persephone
was kidnapped by Pluto
in an attempt to force her to marry him, Demeter became so distraught looking for her daughter that she neglected the Earth which became cold and most plants died. This was the first autumn and winter season, which came back every year even after Persephone had been saved by Hermes because she had eaten a pomegranate that made her Pluto's wife forever, and he demanded she return to him once a year. These myths, including the fact that Ceres is the roundest asteroid (it resembles the Moon) signify that in astrology the placement of Ceres in a birth chart is said to show what the native needs to feel loved and nurtured.
Often simply known as "Pallas," this is the second asteroid discovered & third in size. There are many Pallases
in mythology. Some sources say Pallas
's daughter and Athena
's playmate who was killed and Athena mourned her by changing her name to Pallas Athena & making a wooden statue of her, which Zeus dropped to the Land of Troy where a temple was built in its honor. Others say that Pallas was an old god who combined with Athena. In these respects, Pallas can be interpreted as an indicator of effort. Other astrologers interpret it as an indicator of wisdom, intelligence, healing (perhaps through effort) as the titan named Pallas was a god of these things. This asteroid, like Vesta, is also sometimes called an influencer of Virgo.
This asteroid was the 3rd to be discovered & is 9th in size ranking (1 Ceres, 2 Pallas, 4 Vesta, 10 Hygiea, 704 Interamnia, 511 Davida, 65 Cybele, 52 Europa are considerably bigger and heavier). In mythology Juno
is the Roman equivalent of the Greek Hera
. Hera was a very important goddess in both Greek and Roman culture. She was a wife of Zeus and hailed as the Queen of Gods and Zeus' main concubine (at least the myths imply that this was what she thought herself). She was the goddess of marriages, unions, and was also associated with finance and found cows and peacocks to be sacred. She was also very jealous and aggressive, especially when Zeus was involved with another woman; she would often kill the children Zeus and the other women or goddesses would create together, including attempts to kill Hercules & Dionysus -- or the woman herself. For these reasons, Juno is used in astrology as an indicator of what a native requires to feel satisfied in love or romance, or what is one needs in order to feel their marriage is successful and satisfying. Because of Juno's association with relationships, money, cows and jealousy, it also appears to have an influence of the sign Taurus
This asteroid is second largest in size, fourth to be discovered of which it is the fastest to travel the zodiac and the last asteroid to be counted as a planet. In mythology Vesta
the virgin goddess, the Roman version of Hestia, though she was of higher importance to the Romans, was regarded as one of the most important goddesses of all, though ironically she never was depicted in any visual art (in Greece, some vases with her image however have been found), or at least none of it has ever been found. She was the goddess of hearth, when a baby was born she was the goddess they would ask to bless it and protect the home. In every city & home in Rome there was a sacred fire made to Vesta that was protected & not allowed to go out. Astrologers use Vesta to determine what it is that that you are devoted to and how your sexuality will develop. Vesta, having been a protective virgin goddess is said by some to be an influencer of the sign Virgo
, this is accepted by many in the astrological community, but many prefer to instead of calling the influence an outright rulership an "affinity" or simply do not support this claim. It also seems to bear influence over Scorpio
After the first four asteroids were discovered, there wouldn't be another discovered for 38 years (Astraea). The first four gained popularity as full-fledged planets, but the rapid development of telescopes led to new asteroids being frequently discovered in what is now known as the main-belt. Some astronomers grouped the first 10 asteroids along-side the first four asteroids as planets until the reclassification that was decided upon after the discover of Hygiea, the 10th known asteroid.
This asteroid was the 10th discovered and is fourth in size ranking. In mythology Hygeia was the feminine part and the consort of Asclepios, the Greek god of medicine and a mythological healer strongly connected to the Solar cult of Apollo. It seems that Hygiea rules the health practices and is integrated into medical astrology, but in her negative side has something to bring in cases of depression & anxiety of a higher level than usual. The status of Hygiea
is practically unknown at the moment in western astrology.
