Step-by-step explanation:
Nicolaus Copernicus had a significant impact during the Scientific Revolution as the founder of the heliocentric model of the universe. In his book De Revolutionibus, Copernicus proposed that the Sun, rather than the Earth, was the center of the solar system and that the planets revolve around it. This challenged the then widely accepted geocentric theory and laid the foundation for the modern understanding of the solar system.
