Encyclopedia > Sidereal astrology

Sidereal astrology is the system of astrology used by some western and all Jyotish astrologers which bases their interpretation around the use of the sidereal zodiac. It was introduced to the West by the Irish astrologer Cyril Fagan in 1944 and is practiced by a minority of Western astrologers. Hand-coloured version of the anonymous Flammarion woodcut. ...

Background

Changing position of the vernal equinox. The red line is a section of the apparent path traced by the Sun through the Earth's year. The red/green line is a projection of the Earth's equator on to the celestial sphere. The crossing point of these two lines is the spring equinox. In 1500 BC it was near the end of the Aries constellation, in 500 BC it was near the beginning of the Aries constellation and in AD 150 (the time of Ptolemy) it was in the center of the Pisces constellation.

Sidereal astrology ties its signs of the zodiac to the actual constellations.


The precession of the equinoxes, a phenomenon discovered in ca. 130 BC by Hipparchus and known to Ptolemy, results in a shift between the two systems of about one degree every 70 years. Precession of the equinoxes refers to the precession of the Earths axis of rotation. ... For the Athenian tyrant, see Hipparchus (son of Pisistratus). ...


The vernal equinox lay near the beginning of the Aries constellation around 500 BC, consistent with a Babylonian origin of the system.

While classical tropical astrology is based on the orientation of the Earth relative to the Sun and planets of the solar system, sidereal astrology deals with the position of the Earth relative to both of these as well as the stars of the celestial sphere. The actual positions of certain fixed stars as well as their constellations is an additional consideration in the horoscope. (Over very long astronomical time scales these fixed stars are of course themselves far from stationary). Major features of the Solar System (not to scale): The Sun, the eight planets, the asteroid belt containing the dwarf planet Ceres, outermost there is the dwarf planet Pluto (the dwarf planet Eris not shown), and a comet. ...

Some Sidereal astrologers denounce tropical astrologers for failing to relate to the "actual heavens", seeing in this a fundamental degeneration of the subject (Kenneth Bowser, The Traditional Astrologer magazine, (Ascella), Issue 14, May 1997, pp.23-27 [1]).


Hindu astrology

Main article: Hindu astrology

Traditional Hindu astrology is sidereal, accounting for the shift of the equinoxes by a correction called ayanamsa. The difference between the Hindu and the Western zodiacs is currently around 24 degrees. This corresponds to a separation of ca. 1700 years, or roughly the centuries following Ptolemy, apparently going back to Indo-Greek transmisson of the system.

Signs vs. astronomical constellations of the zodiac

Nearly all astrologers, tropical and sidereal, agree that the ecliptic should be divided into twelve equal segments to form the zodiac; they differ on where the zodiac begins.


Thus, most sidereal astrologers simply divide the ecliptic into 12 equal signs of 30 degrees but approximately aligned to the 12 zodiac constellations. Assuming an origin of the system in 786 BC, this results in an identical system as that of the classical tropical zodiac, shifted by 39.5 days, i.e. if in tropical astrology, Aries is taken to begin at 21 March, sidereal Aries will begin on 30 April. The tropical zodiac is a zodiac based upon tropical time, or the apparent motion of the Sun across the sky over the course of a year. ... March 21 is the 80th day of the year in the Gregorian Calendar (81st in leap years). ... April 30 is the 120th day of the year in the Gregorian calendar (121st in leap years), with 245 days remaining. ...


The 13 astronomical constellations of the ecliptic

A small number of sidereal astrologers wish to include other constellations, such as Ophiuchus, in their zodiac and use thirteen signs instead of twelve[citation needed]. This results in a system completely unrelated to the zodiac as described by Ptolemy. While Ptolemy has of course noted that Ophiuchus is in contact with the ecliptic, he was aware that the twelve signs were just conventional names for 30 degrees segments (especially since the Aries sign had ceased to be in contact with the Aries constellation already in his time). Ophiuchus is one of the 88 constellations, and was also one of the 48 listed by Ptolemy. ...


For the purpose of determining the constellations in contact with the ecliptic, the constellation boundaries as defined by the International Astronomical Union in 1930 are used. For example, the Sun enters the IAU boundary of Aries on April 19 at the lower right corner, a position that is still rather closer to the "body" of Pisces than of Aries. Needless to say, the IAU defined the constellation boundaries without consideration for astrological purposes. Logo of the IAU The International Astronomical Union (French: Union astronomique internationale) unites national astronomical societies from around the world. ...


The dates the sun passed in front of the thirteen astronomical constellations of the ecliptic in are as follows, and are accurate to the year 2002. The dates will increment by one day every 70½ years and already several have changed. The corresponding tropical and sidereal dates are given as well. The plane of the ecliptic is well seen in this picture from the 1994 lunar prospecting Clementine spacecraft. ...

The 21 zodiacal constellations of the planets

Because of their inclination from the ecliptic, the planets are not restricted to the thirteen constellations of the ecliptic. The seven planets (excluding Pluto, which ranges more widely due to its high inclination) pass through 21 constellations. Thus there are 21 astronomical constellations of the zodiac. These are, in addition to the 13 constellations listed above, Cetus, Corvus, Crater, Hydra, Orion, Pegasus, Scutum, and Sextans. The plane of the ecliptic is well seen in this picture from the 1994 lunar prospecting Clementine spacecraft. ... Atmospheric characteristics Atmospheric pressure 0. ...
