The Surya Siddhanta is an ancient Indian astronomical text that is believed to have been composed between the 4th and 5th centuries CE. It contains detailed descriptions of astronomical phenomena, including the motions of the planets, the eclipses of the sun and moon, and the positions of the stars.

The Surya Siddhanta is significant in the context of Babylonian astronomy because it provided accurate predictions of planetary positions and eclipses. These predictions were based on detailed observations of the night sky and were used by Babylonian astronomers to create calendars and horoscopes.

The Babylonian Ephemeris is a collection of astronomical observations and predictions that was compiled over several centuries. It is believed to have been influenced by the Surya Siddhanta, as it contains similar methods for calculating the positions of the planets and eclipses.

The Surya Siddhanta influenced the development of Babylonian astrology in several ways. It introduced the concept of zodiac signs and constellations, which were used to create horoscopes. It also provided methods for casting horoscopes and influenced the development of Babylonian astronomy, which was used to create calendars and horoscopes.

Indian astronomy had a significant impact on the development of Babylonian astronomy. It led to the development of a heliocentric model of the solar system, improved the accuracy of astronomical predictions, introduced the concept of zodiac signs and constellations, and influenced the development of Babylonian astrology.
