It was Copernicus.
In the 1500s, Nicolaus Copernicus further developed the heliocentric explanation for the motion of the planets with his publication of "De revolutionibus orbium coelestium" (On the Revolutions of the Celestial Spheres) in 1543. He proposed that the Sun, not Earth, was the center of the solar system.
Well, let's paint a happy little picture here. In the geocentric model, Earth is believed to be the center of the universe, with all other planets and the Sun revolving around it. On the other hand, in the heliocentric model, the Sun is at the center, and Earth and other planets orbit around it. Both models have their own beauty and history, showing us how our understanding of the cosmos has evolved over time.
The heliocentric model proposed by Copernicus simplified the explanation of planetary motion by placing the Sun at the center of the solar system, allowing for a more straightforward understanding of the orbits of planets. Unlike Ptolemy's geocentric view, which required complex systems of epicycles to account for retrograde motion, Copernicus's model naturally explained these phenomena through the relative motion of Earth and other planets around the Sun. This shift not only reduced the complexity of celestial mechanics but also aligned better with observed astronomical data.
Isaac Newton proposed the three laws of motion and also developed the law of universal gravitation, which explains how the planets orbit the sun. This theory provided a unified explanation for both earthly and celestial motions.
Newton believed in the heliocentric model primarily because it provided a clearer and more coherent explanation of planetary motion than the geocentric model. His laws of motion and universal gravitation supported the idea that the Sun's gravitational pull could account for the orbits of planets, aligning with observations made by astronomers like Copernicus and Kepler. Additionally, the heliocentric model simplified the complexities of retrograde motion and provided a foundation for understanding celestial mechanics. Ultimately, it allowed for a more comprehensive understanding of the solar system's dynamics.

The heliocentric model, proposed by Nicolaus Copernicus, posits that the Sun is at the center of the solar system, with Earth and other planets orbiting around it. This model challenged the geocentric view, which placed Earth at the center. Key summaries include the circular motion of planets, the explanation of retrograde motion as an optical illusion, the relative distances of planets from the Sun, and the realization that Earth rotates on its axis. The heliocentric model laid the groundwork for modern astronomy, influencing later scientists like Galileo and Kepler.

Geocentric motion of planet is that in which earth is at the centre of the universe and all other planets revolving around it.Heliocentric motion of planets is that in which sun is the of universe and other planets revolving around it.In planetary motion all the planets includes Earth revolving around the Sun in their fixed orbit.

the planets accurately. This is because Ptolemy's model relied on epicycles and deferents to explain the apparent retrograde motion of planets, which resulted in discrepancies with the observed phases over time. Copernicus later proposed a heliocentric model that offered a more accurate explanation for the phases of planets.

Johannes Kepler developed the laws of planetary motion.However he was German not Austrian.
Epicycles and deferents were used in early models of the universe to accurately predict the positions of planets in the sky without fully understanding the heliocentric model. They were an attempt to explain the apparent retrograde motion of planets without the advanced knowledge of elliptical orbits.
