Detailed explanation-1: -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-2: -The answer took a while for astronomers to figure out, leading to a debate between what is known as the geocentric (Earth-centered) model and the heliocentric (Sun-centered model).
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 astronomy, heliocentrism is the belief that the Sun is at the centre of the Universe and/or the Solar System. The word is derived from the Greek ( Helios = “Sun” and kentron = “Centre"). Historically, heliocentrism is opposed to geocentrism and currently to modern geocentrism, which places the earth at the centre.
Detailed explanation-5: -Heliocentrism, or heliocentricism, is the astronomical model in which the Earth and planets revolve around a relatively stationary Sun at the center of the Solar System.
Detailed explanation-6: -The Sun is the only star in our solar system. It is the center of our solar system, and its gravity holds the solar system together. Everything in our solar system revolves around it – the planets, asteroids, comets, and tiny bits of space debris.
