What feature distinguishes the heliocentric model from the geocentric model?

Answer 1

The primary feature that distinguishes the heliocentric model from the geocentric model is the position of the Sun and the Earth within the solar system. In the heliocentric model, formulated by Nicolaus Copernicus in the 16th century, the Sun is positioned at the center of the solar system, and the planets, including Earth, orbit around it. In contrast, the geocentric model, which was historically endorsed by figures like Claudius Ptolemy, places the Earth at the center, with the Sun and other celestial bodies revolving around it. This fundamental difference in the arrangement of celestial bodies is what characterizes the two models.
