Explanation:
Detailed explanation-1: -The Copernican heliocentric model was the first widely accepted idea that the sun was the center of the solar system, rather than Earth.
Detailed explanation-2: -Obviously the Earth orbits the Sun. Sure, the textbooks all say that the solar system is heliocentric.
Detailed explanation-3: -In actuality, Copernicus’ heliocentric theory has its problems. First, the planets do not move in exact circles around the Sun, they move in oval paths called ellipses. Another important point is this idea of a center. Contemporary cosmology dispels the notion that the universe has a center at all!
