The Surya Siddhanta is an ancient Indian astronomical text that was translated into Arabic and then into Latin, making it accessible to Assyrian astronomers.

The concept of zero was a major contribution of Indian astronomy to Assyrian astronomy. It allowed for the development of more accurate mathematical calculations and astronomical observations.

The Indian concept of zero enabled the development of positional notation, which allowed for the representation of numbers in a more compact and efficient way.

The astrolabe is an astronomical instrument that was used by Assyrian astronomers to measure the altitude of celestial bodies and to determine the time of day.

The Indian astrolabe allowed Assyrian astronomers to make more accurate measurements of the altitude of celestial bodies, which improved the accuracy of their astronomical observations.

The use of trigonometry was an important technique adopted by Assyrian astronomers from Indian astronomy. It allowed them to solve a variety of astronomical problems, such as calculating the distance to celestial bodies and determining the positions of stars.

The Indian technique of trigonometry enabled Assyrian astronomers to calculate the distance to celestial bodies, which was a significant advancement in astronomical knowledge.

Aryabhata was an Indian astronomer and mathematician who had a significant influence on Assyrian astronomy. His work on astronomy and mathematics was translated into Arabic and then into Latin, making it accessible to Assyrian astronomers.

Aryabhata's primary contribution to Assyrian astronomy was the development of the heliocentric model of the solar system, which placed the Sun at the center of the solar system and the Earth and other planets revolving around it.

Aryabhata's heliocentric model revolutionized the understanding of the solar system by placing the Sun at the center and the Earth and other planets revolving around it, which was a significant departure from the geocentric model that was prevalent at the time.

The concept of the precession of the equinoxes was an important concept adopted by Assyrian astronomers from Indian astronomy. It refers to the gradual shift in the position of the equinoxes over time.

The Indian concept of the precession of the equinoxes enabled Assyrian astronomers to determine the length of the year more accurately, which was important for calendar-making and other astronomical calculations.

The Surya Siddhanta is an Indian astronomical table that was adopted by Assyrian astronomers. It contains a wealth of astronomical data, including the positions of stars, planets, and other celestial bodies.

The Indian Surya Siddhanta provided Assyrian astronomers with accurate data on the positions of celestial bodies, which was essential for astronomical observations and calculations.

Indian astronomy had the greatest impact on Assyrian astronomy in the 5th century BCE, during the reign of King Ashurbanipal.
