* Nicolaus Copernicus: He is credited with reviving the heliocentric model in the 16th century with his book "De Revolutionibus Orbium Coelestium". His work laid the foundation for future astronomers and mathematicians.
* Galileo Galilei: He provided observational evidence for the heliocentric model with his telescope observations of the phases of Venus and the moons of Jupiter. His findings were controversial and led to conflict with the Church.
* Johannes Kepler: He formulated the laws of planetary motion, which described the elliptical orbits of planets around the sun. This was a crucial step in understanding the solar system and further supported the heliocentric model.
* Isaac Newton: He explained the gravitational force that holds the planets in their orbits around the sun. This provided a mathematical and physical basis for the heliocentric model.
It's important to note that the idea of a heliocentric system was not entirely new. Ancient Greek philosophers like Aristarchus of Samos proposed this theory centuries before Copernicus, but it was largely ignored until the Renaissance.
