Glossary term: Prinsip Copernicus

Description: Prinsip ini merupakan hasil akhir dari Model Copernicus untuk Tata Surya. Model "heliosentris" menyatakan planet-planet bergerak mengitari Matahari, menggantikan model yang dipercaya sebelumnya bahwa Bumi berada pada lokasi istimewa di Tata Surya. Secara filosofis, Prinsip Copernicus mewakili pergeseran mendasar dalam persepsi manusia tentang keberadaan kita di Alam Semesta. Pergeseran ini sangat revolusioner pada masa Copernicus. Prinsip Copernicus diperluas dalam kosmologi dan disebut Prinsip Kosmologi, dan menjadi salah satu dasar utama kosmologi modern - tidak ada posisi atau arah yang istimewa di alam semesta teramati. Kedua prinsip ini terus diuji lewat pengamatan pada skala yang berbeda dengan teleskop landas bumi dan teleskop antariksa.

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.
