Sidereal astrology refers to the system of astrology that calculates the position of the planets and stars based on the true astronomical positions in the sky. In contrast to tropical astrology, sidereal astrology considers the fact that the Earth's axis has slowly shifted over time, leading to a slight difference in the position of the stars and planets in the sky. Some synonyms for sidereal astrology include: Vedic astrology, Hindu astrology, Jyotish astrology, and Indian astrology. While there are some differences between these systems, they all share a focus on the precise astronomical positions of the stars and planets.
