What scientist developed that the sun is the center of the universe and earth rotates around the sun?

The scientist who proposed that the Sun is the center of the universe, with the Earth and other planets orbiting around it, was Nicolaus Copernicus. His heliocentric model, published in the 16th century, challenged the long-held geocentric view that placed the Earth at the center. Copernicus's ideas laid the groundwork for modern astronomy and were later supported and expanded upon by scientists like Johannes Kepler and Galileo Galilei.
