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: -The Modern Solar System However, the heliocentric model accurately describes the solar system. In our modern view of the solar system, the Sun is at the center, with the planets moving in elliptical orbits around the Sun. The planets do not emit their own light, but instead reflect light from the Sun.
Detailed explanation-3: -Following the theory of heliocentrism, today we know that Earth, and the other planets of the solar system, are all in orbit around the sun. 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.
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.
