SOLAR SYSTEM

Detailed explanation-1: -Copernican heliocentrism is the astronomical model developed by Nicolaus Copernicus and published in 1543. This model positioned the Sun at the center of the Universe, motionless, with Earth and the other planets orbiting around it in circular paths, modified by epicycles, and at uniform speeds.

Detailed explanation-2: -heliocentrism, a cosmological model in which the Sun is assumed to lie at or near a central point (e.g., of the solar system or of the universe) while the Earth and other bodies revolve around it.

Detailed explanation-3: -In a book called On the Revolutions of the Heavenly Bodies (that was published as Copernicus lay on his deathbed), Copernicus proposed that the Sun, not the Earth, was the center of the Solar System. Such a model is called a heliocentric system.

Detailed explanation-4: -Heliocentric Theory Definition The Sun is the center of our solar system and we revolve around it.

Detailed explanation-5: -However, it was once believed that Earth was at the center of what was thought to be the entire universe, and everything revolved around us– literally. This is now known as the geocentric model, while the heliocentric model puts the sun at the center.

Detailed explanation-6: -Eventually, Galileo came to the same conclusion as Copernicus: the sun, not Earth, was at the center of the universe. In 1632, Galileo published a book in support of the heliocentric theory. Copernicus had previously written in support of the heliocentric theory, but he had been moderate in his claims.
