Glossary term: Revolução Copernicana

Description: A Revolução Copernicana refere-se à substituição do modelo geocêntrico (centrado na Terra) de visualização do Sistema Solar por um modelo heliocêntrico (centrado no Sol). O modelo geocêntrico foi o consenso nas visões científicas europeias por quase dois milênios, embora alguns acreditassem em um modelo heliocêntrico. Essa mudança representou o primeiro passo em direção a um novo modelo para os movimentos dos planetas, luas, estrelas e outros objetos celestes no céu, que ocorreu nos séculos seguintes. O modelo geocêntrico ainda é utilizado para explicar conceitos relacionados à esfera celeste. A Revolução Copernicana recebeu esse nome em homenagem a Nicolau Copérnico, que no século XVI descreveu o modelo heliocêntrico em sua obra seminal De revolutionibus orbium coelestium. Embora se afirme frequentemente que Immanuel Kant foi o primeiro a usar o termo "Revolução Copernicana", a veracidade dessa afirmação é contestada.

Copernicus's heliocentric system

Caption: Sketch of Copernicus's heliocentric model of the Solar System, from his book "De revolutionibus orbium coelestium" (On the revolution of the heavenly spheres) published in 1543. Shown are the Sun as well as the orbits of Mercury, Venus, the Earth (itself orbited by the Moon), Mars, Jupiter and Saturn. The outermost circle represents the sphere of the stars. In this model, the Earth is not special – it is merely one planet, among several, orbiting the Sun. This was the first example for what is now known as the Copernican Principle: that our positions as observers in the universe is not special or privileged in any way. The shift from the geocentric to the heliocentric model of our universe is known as the Copernican revolution.
