Glossary term: Modelo heliocéntrico
Description: El término «heliocéntrico» proviene del griego «helios», que es el nombre del Sol, y «kentro», que significa «centro». Este modelo del Sistema Solar sitúa al Sol en el centro con los planetas orbitando a su alrededor, sustituyendo al modelo geocéntrico (centrado en la Tierra). Aunque el origen del modelo se atribuye a Copérnico en el siglo XVI, Aristarco de Samos desarrolló un modelo heliocéntrico en la Antigua Grecia y astrónomos de la India, Europa y el mundo islámico debatieron sobre tales modelos antes de Copérnico. Las pruebas observacionales a favor del modelo heliocéntrico surgieron de las observaciones telescópicas de Venus realizadas por Galileo. El modelo heliocéntrico original situaba al Sol en el centro geométrico del Sistema Solar; esta visión cambió con las formulaciones matemáticas de Kepler, basadas en los datos de Tycho Brahe, que Newton desarrolló y amplió con su ley de la gravedad.

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.
