Yes, Kepler's laws of planetary motion are still used in modern astronomy to describe the motion of planets and other celestial bodies in our solar system. Kepler's model provides a foundation for understanding orbits and predicting the positions of planets accurately.

The two astronomers who believed in the sun-centered model of the solar system are Nicolaus Copernicus and Johannes Kepler. Copernicus proposed the heliocentric theory in the 16th century, suggesting that the Sun, rather than the Earth, is at the center of the solar system. Kepler later built on Copernicus's ideas in the early 17th century, formulating laws of planetary motion that further supported the heliocentric model.
An example of a heliocentric model is the one proposed by Nicolaus Copernicus, which suggests that the Sun is at the center of the solar system, and the planets, including Earth, orbit around it. This model contrasted with the earlier geocentric model, which placed Earth at the center. Copernicus' heliocentric theory laid the groundwork for modern astronomy and was later supported by observations made by astronomers like Galileo and Kepler.

Ah, my dear friend! Kepler's model of the solar system was heliocentric. You see, he proposed that the sun was at the center, unlike the older geocentric models that placed the Earth at the center. It's truly fascinating how different perspectives can change our understanding of the universe around us.

Copernicus's theory has the Sun at the centre but uses a model of circles and epicycles in the same way that the ancient Ptolemaic one used. Kepler continued to use the idea of having the Sun at the centre but, with the help of Tycho Brahe's new accurate observations, Kepler discovered that elliptical orbits allowed a better fit to the observed positions. Tycho instructed Kepler to work on the orbit of Mars, which was a real piece of luck because Mars's orbit is more elliptical than the other planets' orbits (except Mercury). This led Kepler to the idea of the ellipse, which is the model used today.
The clockwork model of the solar system is called the heliocentric model. It proposes that the Sun is at the center of the solar system with the planets, including Earth, orbiting around it in a set, predictable pattern. This model was proposed by astronomers such as Nicolaus Copernicus and later refined by Johannes Kepler and Galileo Galilei.

Nicolaus Copernicus is the Polish astronomer who proposed the heliocentric model of the solar system, in which the Sun, rather than the Earth, is at the center. His work revolutionized our understanding of the cosmos and laid the foundation for modern astronomy.
Scientists do not believe in the Ptolemaic model because it is based on the idea that the Earth is the center of the universe, which has been disproven by evidence showing that the Earth orbits the Sun, not the other way around. Modern astronomical observations and mathematical models support the heliocentric model proposed by Copernicus, which more accurately explains the movements of planets in our solar system.
