What is evidence for Copernicus?

Evidence for Copernicus' heliocentric model includes the apparent retrograde motion of planets, which can be more simply explained by the Earth’s rotation and its orbit around the Sun rather than by the geocentric model's complex epicycles. Observations of the phases of Venus, similar to those of the Moon, provide further support, as they can only be explained if Venus orbits the Sun. Additionally, the consistent patterns of planetary motions observed over time align more closely with Copernicus' model than with the Ptolemaic system.
