The Rigveda, one of the four Vedas, contains the earliest known records of comet observations in Indian astronomy.

Ancient Indian astronomers primarily relied on naked-eye observations to study comets, as telescopes were not available at that time.

Varahamihira, a renowned Indian astronomer and astrologer, developed a systematic method for recording comet observations in his work, the Brihat Samhita.

In ancient Indian astronomy, comet observations were primarily used for foretelling future events, such as political changes, natural disasters, and the rise and fall of empires.

Bhaskara II, a renowned Indian mathematician and astronomer, provided detailed descriptions of cometary tails in his work, the Siddhanta Shiromani.

Ancient Indian astronomers used star charts to determine the direction of cometary motion by comparing the comet's position relative to the fixed stars.

Aryabhata, a renowned Indian mathematician and astronomer, developed a method for calculating the distance of comets from Earth based on their apparent size and brightness.

Ancient Indian astronomers used numerical calculations based on the comet's orbital period to predict its return.

Varahamihira provided detailed observations of Halley's Comet in his work, the Brihat Samhita, and predicted its return based on its orbital period.

Ancient Indian astronomers primarily used written records to document comet observations, often in the form of astronomical texts and manuscripts.

Bhaskara II provided detailed observations of the Great Comet of 1577 in his work, the Siddhanta Shiromani, and accurately predicted its path and duration.

Ancient Indian astronomers used parallax measurements to determine the size of comets by observing their position from different locations.

Aryabhata developed a method for calculating the orbital period of comets based on their observed motion and position.

Ancient Indian astronomers used chemical analysis to determine the composition of comets by studying the light emitted by their tails.
