He came up with the elegant idea that the Sun was at the centre of the Solar System and that the planets revolved around it.
A slightly more technical answer:
His idea was based on the simplification of the epicyclic model by Ptolemy. The Ptolemic model had many epicycles(over 70) to describe the celestial objects, whereas by putting the Sun at the centre, the number of epicycles were reduced to about 30. I thought I should mention this since this is a deep idea in physics, that nature simplifies and optimizes, more precisely Nature follows the path of least action (in rare cases maximum action).
Hope my answer helped, cheers!:)
