The earth revolves around the sun. The center of the world, according to Copernicus, is the Sun, around which all the planets move, revolving simultaneously around their axes. The stars, according to Copernicus, are motionless and are located at great distances from the Earth and the Sun. Their rotation around the Earth is apparent, and it is connected with the fact that our planet itself rotates around its axis, making one revolution in 24 hours. The stars form a sphere that bounds the universe.
