Copernicus produced an alternative model of the planets that had the Sun at the centre, which contradicted the religious view at the time. The church was unwilling to change its theology without adequte proof. The wisdom of the church's attitude was eventually proved when Copernicus's model was rejected in favour of one discovered by Kepler with elliptical orbits. It also had the Sun at the centre, and when the elliptical orbits were confirmed by Newton's theoretical discoveries the model was generally adopted.
