proposed a heliocentric model of the solar system.

The heliocentric model, which places the Sun at the center of the solar system, was famously proposed by the astronomer Nicolaus Copernicus in the 16th century. This revolutionary idea challenged the long-held geocentric view that put Earth at the center, a belief that had dominated for over a thousand years. Copernicus' work laid the groundwork for future astronomers, including Galileo and Kepler, leading to a profound shift in our understanding of the universe. In the modern world, the heliocentric model has not only shaped our astronomical studies but also influenced the way we navigate space. For example, upcoming missions to Mars and beyond rely on calculations rooted in the heliocentric perspective to determine travel routes and timing. Understanding the mechanics of orbits around our Sun aids in planet exploration, satellite deployment, and even predicting potential asteroid threats to Earth!
