Indian Astronomers and Their Contributions

Aryabhata is widely regarded as the father of Indian astronomy due to his significant contributions to the field. He lived in the 5th century CE and is known for his work on topics such as planetary motion, eclipses, and trigonometry.

Aryabhata proposed the heliocentric model of the solar system, which places the Sun at the center and the planets revolving around it. This model was later adopted by European astronomers such as Copernicus and Galileo.

Varahamihira wrote the treatise 'Surya Siddhanta' in the 6th century CE. This text is considered one of the most important works in Indian astronomy and contains detailed descriptions of planetary motion, eclipses, and other astronomical phenomena.
