In his ''Aryabhatiyabhasya'', a commentary on Aryabhata's ''[[Aryabhatiya]]'', Nilakantha developed a computational system for a partially [[heliocentrism|heliocentric]] planetary model in which Mercury, Venus, [[Mars]], [[Jupiter]] and [[Saturn]] orbit the [[Sun]], which in turn orbits the [[Earth]], similar to the [[Tychonic system]] later proposed by [[Tycho Brahe]] in the late 16th century. Most astronomers of the Kerala school who followed him accepted this planetary model.<ref name=Joseph/><ref>K. Ramasubramanian, M. D. Srinivas, M. S. Sriram (1994).
