who came up with the geocentric model of the solar system?

The most highly developed geocentric model was that of Ptolemy of Alexandria (2nd century ce). It was generally accepted until the 16th century, after which it was superseded by heliocentric models such as that of Nicolaus Copernicus. Compare heliocentrism; Ptolemaic system; Tychonic system.

The geocentric model could not fully explain these changes in the appearance of the inferior planets (the planets between the Earth and the Sun). ... His second law states that for each planet, In ancient geocentric theory, Earth was the center of the universe, and the body around which the Sun and planets revolved.

The nebular hypothesis was first proposed in 1734 by Emanuel Swedenborg and later elaborated and expanded upon by Immanuel Kant in 1755. A similar theory was independently formulated by Pierre-Simon Laplace in 1796.

The Scientific Revolution began in astronomy. Although there had been earlier discussions of the possibility of Earth's motion, the Polish astronomer Nicolaus Copernicus was the first to propound a comprehensive heliocentric theory equal in scope and predictive capability to Ptolemy's geocentric system.

Answer: Scientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a nearby star (called a supernova). ... Squeezing made the cloud start to collapse, as gravity pulled the gas and dust together, forming a solar nebula.

In 1927, the Belgian Catholic priest Georges Lemaître proposed an expanding model for the universe to explain the observed redshifts of spiral nebulae, and calculated the Hubble law. He based his theory on the work of Einstein and De Sitter, and independently derived Friedmann's equations for an expanding universe.

Eudoxus, one of Plato's pupils, proposed a universe where all objects in the sky sit on moving spheres, with the Earth at the centre. This model is known as a geocentric model – often named Ptolemaic model after its most famous supporter, the Greco-Roman astronomer Ptolemy.

Nicolaus Copernicus (1473–1543) was a mathematician and astronomer who proposed that the sun was stationary in the center of the universe and the earth revolved around it.

At the time, people believed in a geocentric model of the universe with the earth at the center. Tycho Brahe (1546-1601) was a Danish nobleman and astronomer, and he was one of the individuals whose work helped overturn that belief in favor of a heliocentric model of the universe, with the sun at the center.

Retrograde motion of the planets was the primary sign that the geocentric model of the solar system did not work. Because it claimed that the earth is the center of the universe, everything from all the other planets to the sun and other stars were thought to orbit earth, which is empirically proven to be incorrect.

The answer took a while for astronomers to figure out, leading to a debate between what is known as the geocentric (Earth-centered) model and the heliocentric (Sun-centered model). ... The Earth was in the center of it all (geocentric), with these planets revolving around it.

After only 18 months, Brahe mysteriously died. Kepler continued to use Brahe's observations and developed his Laws of Planetary Motion with them. Eventually, astronomers like Kepler, Galileo, and Isaac Newton disproved the geocentric view of the earth at the center of the universe once and for all.
