Planetary Motions, Aryabhatta, Kepler

This paper examines the laws on planetary motions in the solar system proposed by Aryabhatta I who lived in Pataliputra I in the 5^th century AD (476-550)  and Kepler (1571-1630). The history of astronomy is reviewed where this contribution by Aryabhatta was not commonly known to public or among the scientific community. Kepler’s laws are very widely known throughout the world.

The findings of this work is that the Aryabhatta’s laws more accurately represent the planetary motions than those of Kepler even though they were written about 1000 years earlier.
