GENERAL KNOWLEDGE

Detailed explanation-1: -Heliocentrism (also known as the Heliocentric model) is the astronomical model in which the Earth and planets revolve around the Sun at the center of the universe. Historically, heliocentrism was opposed to geocentrism, which placed the Earth at the center.

Detailed explanation-2: -Nicolaus Copernicus (1473–1543) was a mathematician and astronomer who proposed that the sun was stationary in the center of the universe and the earth revolved 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: -In it, he proposed that the center of the universe was not Earth, but that the sun lay near it. He also suggested that Earth’s rotation accounted for the rise and setting of the sun, the movement of the stars, and that the cycle of seasons was caused by Earth’s revolutions around it.
