Astrology or Vedic astrology is an ancient science that enables people to understand their destiny and get insights about the future and past happenings of their lives. The study and practice of astrology started when the human civilization began to notice astronomical trends. These trends were found to be somehow connected with the lives of the people.
Astrology and all the astrologers since the initiation of this science have considered studying 9 planets that are: Venus (Shukra), Sun (Surya), Moon (Chandra), Mars (Mangala), Mercury (Budha), Jupiter (Brihaspati), Saturn (Shani), Rahu (north node of the moon), and Ketu (south node of the moon). This is an aberration from the general scientific fact of considering the Sun as a star, the Moon as a natural satellite, and 8 planets.
