Who proved that the Earth revolves around the Sun?

Copernicus is credited with formulating the heliocentric model of the solar system, which posits that the Earth and other planets revolve around the Sun. His work challenged the long-held geocentric view, which placed the Earth at the center of the universe. By providing a mathematical framework and observations that supported his theory, Copernicus laid the groundwork for a revolution in astronomical thought. His ideas were pivotal in shifting the scientific consensus and paving the way for future astronomers like Galileo and Kepler, who built upon his theories with observational evidence and refined models of planetary motion. This foundational contribution to astronomy makes him the key figure in proving that the Earth revolves around the Sun.
