Who rediscovered Aristarchus’s model of a heliocentric solar system?

Nicolaus Copernicus revived the idea that the Sun is at the center of the planetary system, an idea first proposed in antiquity by Aristarchus of Samos. Galileo later provided observations that supported heliocentrism, while Kepler described planetary orbits and Ptolemy developed a geocentric model. Therefore, the correct choice is Copernicus.
