Nicholas Copernicus, a polish priest and astronomer published "On the Revolutions of Celestial Orbs" in 1543. The book argued that motions of the planets could be better explained by assuming that Earth was a planet that orbited the sun. State two reasons why most people rejected this claim.
Many people thought that the sun revolved around the earth because the sun appeared to move in the sky. Another reason is because people thought that the Earth was the center of the universe so it was difficult to accept the idea that the sun revolved around the earth.
