Aryabhata has already been enumerated as one of the most celebrated mathematicians of ancient India. He was also an astronomer ie. one who studies planets and galaxies. It is said that he studied in famous observatories at Nalanda.<ref name=":0" /> In fact, a verse mentions that Aryabhata was the head of an institution at Kusumapura identified as Pataliputra (modern Patna). Since the University of Nalanda, equipped with an astronomical observatory, was in Pataliputra at that time, it is speculated that Aryabhata may have been the head of Nalanda University.<ref name=":3" />
Earlier, it was believed that the earth is fixed at one place. Aryabhata was the first person to correctly insist that the earth constantly rotates about its axis<ref name=":0" /> daily and that the apparent movement of the stars is a relative motion caused by rotation of the earth, contrary to the then prevailing view that the sky rotated. This is indicated in the first chapter of his work, the Aryabhatiya, where he gives the number of rotations of the earth in a Yuga.
The Solar and Lunar eclipses also were scientifically explained by Aryabhata. Instead of the prevailing cosmogony in which eclipses were caused by Rahu and Ketu (identified as pseudo-planetary lunar nodes), he explained eclipses in terms of shadows cast by and falling on earth. He even provided the computation and size of the eclipsed part during an eclipse.<ref name=":3" />
The main objective of studying astronomy was to make correct calendar or panchang, identify the correct season for crops etc. that will help people in farming. Aryabhata contributed to this.<ref name=":0" /> The calendric calculations devised by Aryabhata and his followers have been in continuous use in India for the practical purposes of fixing the Panchanga (the Hindu calendar).<ref name=":3" />
It is in honour of this great astronomer-mathematician that India's first man made satellite is named Aryabhata.<ref name=":0" /><ref name=":3" />
