How was Copernican model was an immediate improvement from Ptolemaic?

It was not an immediate improvement and actually it used more epicycles than the Ptolemaic mode so was more complicated.
But the idea that the Sun is at the centre was taken up by Kepler in his studies of planets' orbits that led to the laws of planetary motion and eventually to the dynamic model of the solar system devised by Newton and others, which is the generally accepted model at the present time.

∙ 11y agoYes. The geocentric model was eventually replaced by the heliocentric model. However, the model of deferents and epicycles was retained because it made reasonably accurate predictions which agreed with observations more accurately than preceding systems. The epicycles of Venus and Mercury are always centered on a line between Earth and the Sun (Mercury being closer to Earth), which explained why they were always near it in the sky. The model was eventually replaced by Kepler's elliptical model only when observational methods (developed by Tycho Brahe and others) became sufficiently accurate to raise doubts about the epicycle model.

The Ptolemaic model did not replace the Copernican model. It was the other way 'round

What is sun centerd model of solar system?
The Sun-centered or heliocentric model of the solar system is called the Copernican model (after Copernicus) and more closely matches the modern astronomical notions. By contrast, the geocentric or Earth-centric model is often called the Ptolemaic.
Did Tycho believe in the Copernican model of heliocentrism?
No, Tycho believed the Earth was at the centre, and he produced an alternative geocentric model that fully explained Venus's phases, which the old Ptolemaic system failed to do.This spoilt Galileo's argument that the Copernican system must be correct and the Sun must be at the centre. However the modern view is that the Sun is at the centre, for reasons that Galileo was not aware of in his lifetime.
He said that the sun is the center of the solar system?
Although there were several thinkers which proposed something like the heliocentric model before him, Copernicus is identified most with the idea; and it took his name, the Copernican system, contrasting with the geocentric model that identified Earth as the center, known as the Ptolemaic model.
Why models of the ealry ptolemy solar system were replaced by the copernican model?
The Ptolemaic Model followed a geocentric model of the solar system. This was then challenged by Nicolaus Copernicus, who claimed a heliocentric model which sparked an integral part of the Scientific Revolution called, the Copernican Revolution. Copernicus' proposal was followed by the Tychonic Model, with attempted to compromise with the geo- and heliocentric models. Then, Kepler improved by suggesting elliptical orbits. The Copernican Revolution came to a close with further speculation from Galileo Galilei and Isaac Newton TL;DR Because they were wrong
What is the centre in the Ptolemaic model of the universe?
Earth
Did it take 2 centuries for copernican models replace ptolemaic model?
yes
How does the Ptolemaic model differ from the modern day model?
The Ptolemaic model has all of the planets moons and stars moving around the Sun. The modern day Copernican model has all the planets moving around the Sun, with the moons moving around the planets, and the Sun and its "system" moving around the Milky Way.

Why is heliocentric and geocentric a theory?
A geocentric theory is one that states the universe is centered by Earth. Geo means earth. The old Ptolemaic Model of the universe has earth as the center. A heliocentric theory is one that is centered by a source of heat. Helio = heat. It basically states that the sun is the center of our galaxy. (Copernican Model)
In the Ptolemaic Greek model of the universe the stars are attached to the?
The stars in the Ptolemaic model of the universe move on or are attached to a celestial sphere.
What is the centre in the Ptolemaic model of the universe?
Earth
Why do scientists not accept the ptolemaic model?
The Ptolemaic model is also known as the geocentric model, where the Earth is at the center of the solar system. Scientists refute this because orbital paths show that the solar system is heliocentric.
What is the copernican model?
The model of the Solar System in which the Sun is in the center and the planets (including Earth) orbit it.
What were 2 of Galileo's greatest accomplishments and why did the Catholic Church react towards him after his ideas were being spread?
Galileo promoted the Copernican model of the planets, with the Sun at the centre. The church told him not to say it was the absolute truth but just to teach it as a theory for predicting the planets' positions, pending more conclusive proof. He discovered things with his telescope that raised doubts about the old Ptolemaic system with the Earth at the centre. The moons of Jupiter were definitely not orbiting the Earth, and the full range of Venus's phases were a major failure of the Ptolemaic theory. Galileo maintained this must prove that the Copernican theory must be right: but Tycho produced a model with the Earth at the center that correctly predicted the full range of Venus's phases.
