Astrology literally means “the Science of the Stars”, from the Greek astrologia: astron (constellation; star) and logia (study of; ordering principle; utterance). It contains both the idea of an organised body of knowledge of the cosmos, along with the way the stars “speak” to us, or give meaning to our lives see Is Astrology Scientific. A person who practices astrology is called an astrologer. A very ancient, but still vital discipline, astrology seeks the meaning and application of the influences of the planets, stars and other celestial phenomena in our lives. Astrology and astronomy have in modern times become separate studies, though for most of human history they were two sides of the same coin see How does Astrology differ from Astronomy.
Astrology, for predicting and timing of fortunate and unfortunate periods, divining fate and destiny, and determining the cultural myths and stories that revealed the pathway to realisation of the spirit navigation, for getting around in unfamiliar territory, especially at sea and a mixture of chronology, religion and politics, for planning agricultural, political and religious events, such as sowing and reaping, timing of social and religious festivals, ceremonies, military action, and so on.
My answers in regard to Astrology, could be very different from what you may expect from a typical astrologer. Since I am not a professionally practicing astrologer but a seeker in the quest for knowledge, I have always tried to find answers which satisfies the scientist in myself. The job for which I am trained. Believe me that I used to be, and still am, a much more a skeptic than you think I could ever be and expect from a person.
Astrology consists of a number of belief systems which hold that there is a relationship between astronomical phenomena and events in the human world. In the West, astrology most often consists of a system of horoscopes that claim to predict aspects of an individual’s personality or life history based on the positions of the sun, moon, and other planetary objects at the time of their birth. Many cultures have attached importance to astronomical events, and the Indians, Chinese, and Mayans developed elaborate systems for predicting terrestrial events from celestial observations.
Astrology is a pseudoscience, and as such is not taken seriously by the academic or scientific communities. Some scientific testing of astrology has been conducted, and no evidence has been found to support either the premises or purported effects outlined in astrological tradition. Furthermore, there is no proposed mechanism of action by which the positions and motions of stars and planets could affect people and events on Earth that does not contradict well understood, basic aspects of biology and physics.
