A mechanical working model of the solar system is called an orrery. Many observatories have them, as do thousands of individuals.
Galileo supported the heliocentric model, which placed the Sun at the center of the solar system with planets, including Earth, orbiting around it. He provided evidence for this model through his observations of the phases of Venus, which could only occur in a heliocentric system where Venus orbits the Sun.
Ptolemy's model, known as the geocentric system, posits that the Earth is at the center of the universe, with celestial bodies, including the Sun, Moon, and planets, moving in circular orbits around it. To account for the observed retrograde motion of planets, he introduced epicycles—small circles along which planets moved while simultaneously orbiting the Earth on larger circles called deferents. This complex system aimed to accurately predict the positions of celestial bodies, despite its eventual replacement by the heliocentric model proposed by Copernicus.
The leader of the scientific revolution who published "On the Heavenly Bodies" (also known as "De revolutionibus orbium coelestium") was Nicolaus Copernicus. His work, published in 1543, proposed the heliocentric model of the solar system, asserting that the Earth and other planets revolve around the Sun. This groundbreaking idea challenged the long-held geocentric view and laid the foundation for modern astronomy. Copernicus's theories significantly influenced later scientists, including Galileo and Kepler.
It is the theory in which the earth is the center of the universe and that all the planets revolve around it including the sun. this theory was developed by Aristotle.Geocentric theory basically stated that the Earth was at the center of the universe, and that the sun, moon, planets, and other heavenly bodies revolved around it. This theory was believed extensively during the middle ages.
The geocentric model can explain the apparent motion of celestial bodies, such as the Sun, Moon, and stars, appearing to move across the sky from east to west. This model posits that the Earth is at the center of the universe, and as these bodies orbit around it, they create the illusion of daily motion. Additionally, the retrograde motion of planets can be accounted for by the relative positions and movements of Earth and the other planets in this framework. However, this model struggles to explain some phenomena, leading to the eventual acceptance of the heliocentric model.

No, William Harvey did not write "The Revolution of Heavenly Bodies." This work was written by Nicolaus Copernicus, who proposed the heliocentric model of the universe in which the Earth and other planets revolve around the sun. William Harvey, on the other hand, is known for his discoveries regarding the circulation of blood in the body.
Aristotle's model of the universe took into account the charted movements of the heavenly bodies, but was complicated by the assumption that Earth lay at the center of the universe.

No, all the planets in our solar system revolve around the sun. The idea that all celestial bodies revolve around the Earth is known as the geocentric model, which has been replaced by the heliocentric model proposed by Copernicus in the 16th century.
