Astrology literally means “the science of the stars”, from the Greek astrologia. Astron (constellation; star) and logia means (study of; ordering principle; utterance). Astrologer is a person who practices astrology.
Astrology is an ancient science which explains planetary motion and position and their effect on human beings and other entities. Earlier astrology was only based on motion of planets and stars, but later it started including zodiac signs also. There are 27 constellations including 12 zodiac signs, 9 planets and 12 houses and each house has its own impact on human life. The snapshot of signs and planets are called horoscope.
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 consists of a system of horoscopes that predict aspects of an individual’s life history and personality based on the positions of planetary objects at the time of their birth.
