What astrological fact did the aryabhata demonstrate awareness of?

Aryabhata, the ancient Indian mathematician and astronomer, demonstrated awareness of the Earth's rotation on its axis. He emphasized the concept that the apparent movement of celestial bodies is due to the rotation of the Earth, rather than the movement of the bodies themselves. This understanding was revolutionary for his time and laid the groundwork for future astronomical studies. Additionally, he accurately calculated the length of the year and the positions of celestial bodies, showcasing his advanced knowledge of astronomy.
