He thought that the sun was the center
He believed the sun was the center of the solar system and set out, with much difficulty, in proving it to the Catholic church and the scientific world.
The clockwork model of the solar system is called the heliocentric model. It proposes that the Sun is at the center of the solar system with the planets, including Earth, orbiting around it in a set, predictable pattern. This model was proposed by astronomers such as Nicolaus Copernicus and later refined by Johannes Kepler and Galileo Galilei.
To give you a basic idea how the solar system is set up.
Nicolaus Copernicus was the first to establish the theory that the Sun, and not the Earth, was the center of the solar system. This heliocentric theory changed the former one set in 150 AD by Ptolemy. It had a huge impact, forcing the Catholic Church, mired in Ptolemaic thought and timekeeping, to admit wrong and institute change.
Our solar system is called the "Solar System" which consists of the Sun and all the astronomical objects orbiting around it, including planets, moons, asteroids, comets, and dust.
Nicolaus Copernicus will be remembered for introducing the heliocentric model of the solar system, which placed the Sun at the center and the planets orbiting around it. This challenged the prevailing geocentric view and laid the foundation for modern astronomy. His work revolutionized our understanding of the universe and set the stage for further scientific advancements.

There is no planet where the sun does not rise and set. All planets in our solar system experience day and night due to rotation on their axes.
