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: -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.

Detailed explanation-4: -He discovered that the sun has sunspots, which appear to be dark in color. Galileo’s discoveries about the Moon, Jupiter’s moons, Venus, and sunspots supported the idea that the Sun-not the Earth-was the center of the Universe, as was commonly believed at the time.

Detailed explanation-5: -The word “helios” in Greek means “sun.” Heliocentric means that the sun is at the center. A heliocentric system is one in which the planets revolve around a fixed sun. Thus Mercury, Venus, the Earth, Mars, Jupiter and Saturn all revolve around the sun.
