Ptolemy was the first person to introduce the theory of a geocentric universe, a universe in which everything revolves around the earth itself. But in 1543, Nicolas Copernicus was the first person to introduce and prove the idea that the universe is heliocentric, a universe in which everything revolves around the sun.
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.
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.
Heliocentric
The scientist made the heliocentric model of the solar system. It is a word for the graphical model of our solar system.
The Ptolemaic system belived that the earth was the center of everything and all the planet and sun traveled around it and the copernican system belived that the sun was the center of everything and the planets and traveled around the sun.
The Geocentric or Ptolemaic Model put the earth at the center of the Universe. The Heliocentric Model postulated by Copernicus and, before him, Aristarchus, places the Sun at the center of the Solar System. Galileo's observations proved the validity of the Heliocentric Model.
The main idea in the Ptolemaic system was that the Earth was at the center of the universe, with the Moon, Sun, planets, and stars orbiting around it in perfect circles. This geocentric model dominated Western astronomy until it was eventually replaced by the heliocentric model proposed by Copernicus.
The name is of the general theory where celestial objects revolve around the Earth is known as the Ptolemaic system.
The Ptolemaic system, developed by the ancient Greek astronomer Claudius Ptolemy, is a geocentric model of the universe that posits the Earth as the center of all celestial bodies. In this system, the Sun, Moon, planets, and stars orbit the Earth in complex paths called epicycles. This model was widely accepted for many centuries until it was eventually replaced by the heliocentric model proposed by Copernicus, which placed the Sun at the center of the solar system. The Ptolemaic system exemplifies the historical progression of astronomical thought and the quest to understand our place in the universe.
The proposed the heliocentric system.
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.
in a heliocentric system earth and the other planets revolving planet's a geocentric system ,earth is at the center of the revolving planets
If you mean what scientist created the heliocentric theory, it was Nicolaus Copernicus. Based on astronomical observations, he determined that the Ptolemaic geocentric theory was incorrect, and replaced it with his own heliocentric theory, which placed the sun at the center of the universe, and had planets orbiting the sun.

Heliocentric = The Sun is at the center of our solar system. Geocentric = The Earth is at the center of our solar system. Insisting the Sun is at the center, which it is, once very much angered the church.
Galileo did not directly provide evidence for the heliocentric principle but he did discover important evidence that raised doubts about the Ptolemaic system with the Earth at the centre. First, he discovered the moons of Jupiter, and these were the first objects discovered that definitely orbited round something that was not the Earth. That was one thing. Secondly, he discovered that Venus has a gibbous phase when seen from Earth in certain positions in its orbit. This is not explained by the Ptolemaic system because Venus cannot go round behind the Sun in the Ptolemaic system. Again this did not prove the heliocentric principle because Tycho Brahe came up with an intermediate system that had Mercury and Venus orbiting round the Sun, and then the Sun and the other planets orbit round the Earth. So this was still a geocentric system that explained all Venus's phases. Therefore Galileo did not have enough evidence to prove the heliocentric principle, and after his trial he recanted. But 60-70 years later enough new evidence had been gathered to convince most people that the Sun is at the centre, as we believe now.
Nicolaus Copernicus proposed a heliocentric model of the solar system, which deviated from the geocentric model in the Ptolemaic system. In Copernicus' model, the Sun, not Earth, was at the center of the universe, with the planets, including Earth, revolving around it.
