The man who managed to create a new model of the Universe was the great Polish astronomer Nikolai Copernicus (1473-1543). Observations of stars and planets, the study of the works of ancient thinkers and his contemporaries, complex mathematical calculations allowed him to conclude that the Earth revolves around the Sun. The center of the world, according to Copernicus, is the Sun, around which all the planets move, rotating 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. Stars form the sphere that borders the universe.
