The science of Astrology has great antiquity behind it. Vedas which are said to be the oldest religious literature available has references to this science. Astrology has great importance attached to it as "Vedanga Jyothisha". That means "Jyothisha or Astrology" is one of the limbs of the "Vedas" (1500 B.C.). Hindus were the original masters who had the thorough knowledge of astronomy and many rituals and religious rites were related to the position of planets and their motions. It was expected of all those who wanted to understand Vedas, to be well versed with the knowledge of astronomy and astrology.
The earliest astronomical works such as Surya Siddanta and Vedanga Jyothisha are more then five thousand years old. Long before Kepler, Copernicus, Brahe, Galilio and other galaxy of astronomers were born, the Hindu sages had already gained much knowledge on the stellar or planetary universe.
