The heliocentric model of the solar system places the ________ at the centre of the solar system.

The heliocentric model of the solar system places the Sun at the center of the solar system. This model, proposed by Nicolaus Copernicus in the 16th century, revolutionized our understanding of the cosmos by suggesting that the Earth and other planets revolve around the Sun, rather than the Earth being the center of the universe. This idea was later supported by the work of astronomers such as Galileo Galilei and Johannes Kepler, who provided observations and mathematical descriptions of planetary motion. The heliocentric theory laid the foundational framework for modern astronomy and significantly changed humanity’s perspective on its place in the universe.
