"Near the Sun is the center of the universe. Moreover, since the Sun remains stationary, whatever appears as a motion of the Sun is really due rather to the motion of the Earth."
— Nicolaus Copernicus
Near The Sun Is The Center
Near the Sun is the center of the universe. Moreover, since the Sun remains stationary, whatever appears as a motion of the Sun is really due rather to the motion of the Earth.
About this quote
Nicolaus Copernicus stated this conclusion explicitly in Book I, Chapter 10 of De revolutionibus orbium coelestium (1543), in a chapter titled "The Order of the Heavenly Spheres." This passage presents the core of the Copernican revolution: that the apparent annual motion of the Sun is an illusion created by Earth's orbital motion around it. The chapter also establishes the correct order of the planets from the Sun — the first time the solar system was correctly described in print.
