This is the Copernican Armillary Sphere. The Armillary Sphere is like a globe of the universe. This Copernican Armillary Sphere shows the Copernicus's theory of the sun being the central point of the universe. Before the Copernican Armillary Sphere, there was the Ptolemaic Armillary Sphere showing the Earth as the center point.

This is a model/diagram of the heliocentric theory proposed by Nicolaus Copernicus. It shows the idea of the solar system orbiting around the Sun and not the Earth. After seeing this model Galileo started to support the theory as well.

Nicolaus Copernicus was a Polish astronomer who proposed that the planets have the sun as the fixed point to which their motions are to be referred. Nicolaus Copernicus was born on February 19, 1473, at Toruń, Royal Prussia, Poland, and died on May 24, 1543 at Frombork, Poland.

Heliocentrism is the theory that Nicolaus Copernicus came up with. The theory is that the center of the universe is not the Earth, which was believed, but the Sun. Which also meant that all the planets including Earth orbited the Sun.

What is Heliocentrism?

When Nicolaus Copernicus first shared his theory in 1543 it was denied. The reason why it was denied was because its proponents could not explain why the relative positions of the stars seemed to remain the same despite the Earth's changing viewpoints as it moved around the Sun. However after about a decade Heliocentism was accepted from the discoveries of Galileo Galilei, Johannes Kepler, and Sir Isaac Newton.

Was Heliocentrism Accepted or Denied?

Nicolaus Copernicus

Nicolaus Copernicus came up with the theory of Heliocentrism by very carefully studying planetary models. After analyzing Ptolemaic model, he figured out that it was inaccurate. The reason why Copernicus thought the Ptolemaic model was inaccurate was because he thought it was too complicated and unrealistic. The reason why the Ptolemaic model is so complicated is because it took advanced trigonometry to explain how the planets moved.
