Copernicus

Nicolaus Copernicus was born on February 19, 1473 in Torun, Poland and died May 24, 1543 in Frauenburg.

they believed that the earth was the center.

In physics, theories are not mathematically proved but instead they are compared with physical observations to see if they are correct. Copernicus's theory was not just an idea that the Sun is at the centre, but also a detailed mathematical system of circle and epicycles that provided a model of the planets' orbits. At the time of Copernicus and for a time afterwards, his theory was used to predict the planets' positions, and when the predictions were found to be 'correct', the theory was considered 'proved' .

But later Tycho Brahe developed more accurate measurement techniques, and using those he discovered small errors in the predicted positions of the planets. That led to Kepler's work and the discovery of elliptical orbits.

Nothing. Copernicus died years before Kepler was born.

they proved that the earth rotate around the sun not the other way making people doudt the ancient greek authorities

Because he didn't invent the Telescope so he saw it from his naked eye

Nicolaus Copernicus was a mathematician and astronomer who lived 1473-1543 developed the heliocentric model. Meaning he believed the earth revolved around the sun this contradicted popular belief at the time.

Geocentric theory

Copernicus' parents were Nicolaus Koppernigk - of which 'Copernicus' is the Latin form - and Barbara (Watzenrode).

Nikolaus Kopernikus was a Renaissance mathematician and astronomer who formulated a model of the universe that placed the Sun rather than the Earth at the center of the universe.The publication of this model in his book De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres)

Nicholas Copernicus 1473-1543 was a Polish priest and astronomer who created an alternative model of the planets which put the Sun at the centre, instead of the Earth as generally accepted at that time.
Kepler's model is the one we use today, and it has the Sun at the centre, like the Copernican model, but all the other details of Copernicus's theory were rejected in favour of elliptical orbits.

Heliocentrism is the astronomical theory that the Earth and planets revolve around the Sun and that the Sun is stationary at the center. The geocentric model is the theory that the Earth is the center of the universe and other objects go around it.

Copernicus published his heliocentric theory in 1543 in his book "De Revolutionibus Orbium Coelestium" (On the Revolutions of the Celestial Spheres).

The Catholic Church initially opposed the heliocentric theory proposed by Copernicus, as it contradicted the geocentric view that was widely accepted and aligned with certain scriptural interpretations. Galileo's support of the theory led to significant conflict with the Church, culminating in his trial and condemnation for heresy in 1633. The Church's resistance stemmed from concerns about its authority and the implications of challenging established doctrines. Over time, however, these tensions contributed to a broader dialogue about science and faith, eventually leading to a reevaluation of the Church's stance on scientific inquiry.

The Sun was assumed to be at the centre until it was discovered in the 19th century that the Sun is only an insignificant star among a billion in our own galaxy.

In modern theory the Sun is at the centre of the Solar System.

Both Ptolemy and Copernicus used the circle as the basic element of the orbits, but they both knew that a simple circle was not correct in describing the movements of the planets accurately.

The way they worked round the problem was to use epicycles. An epicycle was a small circle whose centre moved round the main circle, and the planet remained stationary on the epicycle. In other words the line joining the planet to the centre of the epicycle stays in the same direction all the time. This is actually a good approximation to an elliptical orbit because it reproduces the effect of the planet moving closer and further away once during one revolution, and geometrically it is equivalent to having the planet going round a circle but with the Sun offset from the centre (by a different amount for each planet).

That is why the model lasted for as long as it did - 1500 years, until Tycho Brahe made observations and recorded the planets' positions with such high accuracy that Kepler was able to deduce the ellipse as the more correct form for planets' orbits. He did this by studying Tycho's measurements of the orbit of Mars, which has a higher eccentricity factor than all the main planets except Mercury which is difficult to observe, and there was just enough difference for Kepler to spot it.

The major difference between Ptolemy's model and Copernicus's was that the Earth was at the centre when the Ancient Greeks studied the problem, and the Sun had an orbit, while Copernicus in the early 16th century imagined the Sun at the centre. Later scientific discoveries by Newton and his successors demonstrated the sun-centred theory as superior.

Copernicus did not reject the idea that planetary orbits around our Sun were circular.

I don't know, BUT the sun is NOT the center of the universe. We can't even see the whole universe, so there's absolutely no way of telling where the center is.

I am quite sure there are.

Intelligent support systems (ISS), sometimes referred to as expert systems, are one of the more advanced forms of information systems.

A sun-centered solar system is called a heliocentric solar system. In a heliocentric system, the Sun is at the center and the planets, including Earth, orbit around it. This model was proposed by Nicolaus Copernicus in the 16th century, replacing the earlier geocentric model where Earth was believed to be the center of the universe.
