Astrology (from Greek: αστήρ, αστρός (astér, astrós), "star", and λόγος, λόγου (lógos, lógou), "treatment", "theory", "study": lit. study on the stars) is a group of systems, traditions, and beliefs in which knowledge of the relative positions of celestial bodies and related details is held to be useful in understanding, interpreting, and organizing information about personality, human affairs, and other terrestrial matters. A practitioner of astrology is called an astrologer, or an astrologist. Numerous traditions and applications employing astrological concepts have arisen since its earliest recorded beginnings in the 2nd millennium BCE.[1] It has played a role in the shaping of culture, early astronomy, and other disciplines throughout history.
Historically, astrology and astronomy were often indistinguishable, with the desire for predictive and divinatory knowledge one of the primary motivating factors for astronomical observation. Astronomy began to diverge from astrology after a long period of gradual separation from the Middle Ages up until the 18th century, and has since distinguished itself as the scientific study of astronomical objects and phenomena, placing no significance on these phenomena's supposed astrological correlation.
Proponents have defined astrology variously, as a symbolic language,[2][3] an art form,[4] a science,[4] and a method of divination.[5][6] The scientific community generally considers astrology as a pseudoscience or superstition.[7][8] While there is no scientific evidence behind the principles of astrology, belief in astrology is widespread.

Core beliefs
The core beliefs of astrology were prevalent in most of the ancient world and are epitomized in the Hermetic maxim "as above, so below". Tycho Brahe used a similar phrase to summarize his studies in astrology: suspiciendo despicio, "by looking up I see downward".[13] Although the principle that events in the heavens are mirrored by those on Earth was once generally held in most traditions of astrology around the world, in the West there has historically been a debate among astrologers over the nature of the mechanism behind astrology. The debate also covers whether or not celestial bodies are only signs or portents of events, or if they are actual causes of events through some sort of force or mechanism.[citation needed]
Although the connection between celestial mechanics and terrestrial dynamics was explored first by Isaac Newton with his development of a universal theory of gravitation, claims that the gravitational effects of the celestial bodies are what accounts for astrological generalizations are not substantiated by scientific research, nor are they advocated by most astrologers.[citation needed]
A common belief held by astrologers is that the positions of certain celestial bodies either influence or correlate with human affairs.
Most astrological traditions are based on the relative positions and movements of various real or construed celestial bodies and on the construction of celestial patterns as seen at the time and place of the event being studied. These are chiefly the Sun, Moon, the planets, the stars and the lunar nodes. The frame of reference for such apparent positions is defined by the tropical or sidereal zodiac of twelve signs on one hand, and by the local horizon (ascendant) and midheaven on the other. This latter (local) frame is typically further divided into the twelve astrological houses. Furthermore, the astrological aspects are used to determine the geometric/angular relationship(s) between the various celestial bodies and angles in the horoscope.
The claim of astrology to predict future trends and developments, or predictive astrology, is based on two main methods: astrological transits and astrological progressions. In astrological transits the ongoing movements of the planets are interpreted for their significance as they transit through space and the horoscope. In astrological progressions the horoscope is progressed forward in time according to set methods. Most modern astrologers no longer try to forecast actual events, but focus instead on general trends and developments. Skeptics respond that this allows astrologers to avoid making verifiable predictions, and gives them the ability to attach significance to arbitrary and unrelated events, in a way that suits their purpose. [14]
In the past, astrologers often relied on close observation of celestial objects and the charting of their movements. Modern astrologers use data provided by astronomers which are transformed to a set of astrological tables called ephemerides, showing the changing zodiacal positions of the heavenly bodies through time.

Traditions
There are many traditions of astrology, some of which share similar features due to the transmission of astrological doctrines between cultures. Other traditions developed in isolation and hold completely different doctrines, although they too share some similar features due to the fact that they are drawing on similar astronomical sources.
Current traditions
The main traditions used by modern astrologers are:
* Indian astrology
* Western astrology
* Chinese astrology
Indian and Western astrology share a common ancestry as horoscopic systems of astrology, in that both traditions focus on the casting of an astrological chart or horoscope, a representation of celestial entities, for an event based on the position of the Sun, Moon, and planets at the moment of the event. However, Indian astrology uses the sidereal zodiac, linking the signs of the zodiac to their original constellations, while Western astrology uses the tropical zodiac. Because of the precession of the equinoxes, over the centuries the twelve zodiacal signs in Western astrology no longer correspond to the same part of the sky as their original constellations. In effect, in Western astrology the link between sign and constellation has been broken, whereas in Indian astrology it remains of paramount importance. Other differences between the two traditions include the Indian use of 27 (or 28) nakshatras or lunar mansions, which have been used in Indian astrology since Vedic times, and the system of planetary periods known as dashas.
In Chinese astrology a quite different tradition has evolved. By contrast to Western and Indian astrology, the twelve signs of the zodiac do not divide the sky, but rather the celestial equator. The Chinese evolved a system where each sign corresponds to one of twelve 'double-hours' that govern the day, and to one of the twelve months. Each sign of the zodiac governs a different year, and combines with a system based on the five elements of Chinese cosmology to give a 60 (12 x 5) year cycle. The term Chinese astrology is used here for convenience, but it must be recognised that versions of the same tradition exist in Japan, Vietnam, Thailand and other Asian countries.
In modern times, these traditions have come into greater contact with each other, notably with Indian and Chinese astrology having spread to the West, while awareness of Western astrology is still fairly limited in Asia. Astrology in the Western world has diversified greatly in modern times. New movements have appeared, which have jettisoned much of traditional astrology to concentrate on different approaches, such as a greater emphasis on midpoints, or a more psychological approach. Some recent Western developments include:
* Modern tropical and sidereal horoscopic astrology
* Cosmobiology
* Psychological astrology
* Sun sign astrology
* Hamburg School of Astrology
o Uranian astrology, subset of the Hamburg School
* Indian astrology

Historical traditions
Throughout its long history, astrology has come to prominence in many regions and undergone developments and change. There are many astrological traditions that are historically important, but which have largely fallen out of use today. Astrologers still retain an interest in them and regard them as an important resource. Historically significant traditions of astrology include:
* Arab and Persian astrology (Medieval, near Eastern)
* Babylonian astrology (Ancient, near East)
* Egyptian astrology
* Hellenistic astrology (Classical antiquity)
* Mayan astrology

Esoteric traditions
Many mystic or esoteric traditions have links to astrology. In some cases, like Kabbalah, this involves participants incorporating elements of astrology into their own traditions. In other cases, like divinatory tarot, many astrologers themselves have incorporated the tradition into their own practice of astrology. Esoteric traditions include, but are not limited to:
* Alchemy
* Chiromancy
* Kabbalistic astrology
* Medical astrology
* Numerology
* Rosicrucian or "Rose Cross"
* Tarot divination
Historically, alchemy in the Western World was particularly allied and intertwined with traditional Babylonian-Greek style astrology; in numerous ways they were built to complement each other in the search for occult or hidden knowledge.[citation needed] Astrology has used the concept of the four classical elements of alchemy from antiquity up until the present day. Traditionally, each of the seven planets in the solar system known to the ancients was associated with, held dominion over, and "ruled" a certain metal.

The zodiac
The zodiac is the belt or band of constellations through which the Sun, Moon, and planets transit across the sky. Astrologers noted these constellations and so attached a particular significance to them. Over time they developed the system of twelve signs of the zodiac, based on twelve of the constellations they considered to be particularly important. The Western and Indian zodiac signs have a common origin in the tradition of horoscopic astrology, and so are very similar in meaning. In China on the other hand, the development of the zodiac was different. Although the Chinese too have a system of twelve signs (named after animals), the Chinese zodiac refers to a pure calendrical cycle, as there are no equivalent constellations linked to it like the Western or Indian zodiacs. The common choice of twelve zodiac signs is understandable considering the interaction of the Sun and Moon was central to all forms of astrology. Twelve cycles of the Moon — the months — coincided with one solar year, making twelve a natural choice.
The majority of Western astrologers base their work on the tropical zodiac which divides the sky into twelve equal segments of 30 degrees each, beginning with the first point of Aries, the point where the line of the earth's celestial equator and the ecliptic (the Sun's path through the sky) meet at the northern hemisphere spring equinox. Due to the precession of the equinoxes, the slow changing of the way Earth rotates in space, the zodiacal signs in this system bear no relation to the constellations of the same name but stay aligned to the months and seasons.
Practitioners of the Indian astrological tradition and a minority of Western astrologers use the sidereal zodiac. This zodiac uses the same evenly divided ecliptic but approximately stays aligned to the positions of the observable constellations with the same name as the zodiacal signs. The sidereal zodiac differs from the tropical zodiac by an offset called the ayanamsa which steadily increases as the equinoxes drift further.
