Answer 1

The feature that distinguishes the heliocentric model from the geocentric model is **the placement of the Sun at the center of the solar system**. In the heliocentric model, the Sun is at the center, and the planets, including Earth, orbit around it. In contrast, the geocentric model places the Earth at the center, with the Sun and other celestial bodies orbiting around it.
