Precession of the equinoxes

Precession Of The Equinoxes: The gradual westward shift (about 50' each year) of the equinoctial points along the ecliptic due to the ecliptic due to the rotational movement of the poles of Earth's axis.

actually begins here.
*Since the Earth is not a perfect sphere (see glossary, "oblateness"), the Sun and Moon pull on it unevenly.

Precession of the Equinoxes
This term refers to way the equinoxes move backwards very slowly through the zodiac, due to a wobble in the Earth's rotation.

Precession of the Equinoxes: Refers to the slow movement of the Vernal Equinox in a backward motion in relation to the constellations which make up the sidereal zodiac.

The world time should follow the precession of the Equinoxes, but this would entail not only the relocation of the Observatory every 70 or 700 years but of all the time zone meridians - obviously a difficulty not easily overcome.

They fixed the calendar (both lunar and solar), described the zodiac and asterisms in great detail, calculated precisely the precession of the equinoxes, established the general laws of the stellar movements and observed and predicted the eclipses.

It goes something like this: "Due to the precession of the equinoxes, the Sun at a given time of year is no longer in the sign it was 2,000 years ago. Therefore you are not really an Aries, but a Pisces! ...

I was trying to make a point that Tropical Astrologers should take into account the precession of the equinoxes. The system they used from Ptolemy was aligned with the stars 2000 years ago. It's important to maintain that.

Of these, the last movement known as the precession of the equinoxes is responsible for the development of the concept of a sidereal or fixed zodiac that was widely used for horoscopic calculations in Indian astrology.

This movement is called the Precession of the Equinoxes. The current location (2009) of the Vernal Point in the sidereal zodiac is at approximately 5 degrees of sidereal Pisces.

(190-120) Hipparchus- figures out the precession of the Equinoxes. Hipparchus also composed a star catalog listing some 1000 stars. (150) Mystical writings of Nechepso in Egypt. (135) Birth of Posidonius - teacher of astrology to the Romans.

These ages are based on the precession of the equinoxes that shifts the alignment of the Earth to the ecliptic plane. And there's great interest in this current age as a time of the old world dying, and a new one being born.

The Sidereal zodiac takes into account the precession of the equinoxes and is the zodiac used by astronomers. The Tropical is based on the traditional positions of the demarcations of the zodiac and is primarily used by astrologers.

The two zodiacs are constantly drifting farther apart due to what is called the precession of the equinoxes (they are currently about 24 degrees apart).

Zodiac: The circle of signs that follows the apparent path of the Sun (ecliptic). Also called the movable zodiac because it shifts slightly each year relative to the constellations of the sidereal zodiac. See also Precession of the Equinoxes.

The classical Greeks named the Tropical Signs for the constellations that, at that time, approximately coincided. Due to the Precession of the Equinoxes, the Signs and the Constellations no longer coincide. See also Zodiac.

Despite the fact that their arguments are based on an irrefutable natural phenomenon (the 'precession of the equinoxes'), they have it all so turned around that they don't know what they're talking about. And therein lies a tale . . .

Hipparchus (fl. 146-127 BCE) realized the implications of this phenomenon, discerning the process known as the precession of the equinoxes, whereby the Vernal Equinox - the point at which the Sun on its apparent course defining the ecliptic, ...

In Tropical Astrology the qualities associated with the signs are linked to the seasons, rather than to the fixed stars, and therefore the precession of the equinoxes and the growing difference between the Tropical Signs and the relative positions ...
