The Heliocentric Model

The heliocentric model is a scientific theory that places the Sun at the center of our solar system, with the Earth and other planets orbiting around it. Proposed by Nicolaus Copernicus in the 16th century, this model challenged the earlier geocentric view, which suggested the Earth was the center. The heliocentric model helped explain the apparent movement of celestial bodies in the sky more accurately. It laid the groundwork for modern astronomy, influencing key figures like Galileo and Kepler, and it ultimately transformed our understanding of the universe and our place within it.
