If the Earth actually spun on an axis (as required in a heliocentric system to stars I think the example of Aristarchus is a poignant one. His remarkable work, On the Revolutions of Heavenly Spheres, stands as one of the greatest intellectual revolutions of all time, and profoundly influenced, among others, Galileo and Sir Isaac Newton. Nicolas Copernicus was born in 1473 and died in 1543. Who is Nicolaus Copernicus? Before Copernicus, educated people believed without a doubt that the sun and the planets traveled around Earth.

Ptolemaic system, also called geocentric system or geocentric model, mathematical model of the universe formulated by the Alexandrian astronomer and mathematician Ptolemy about 150 CE and recorded by him in his Almagest and Planetary Hypotheses.The Ptolemaic system is a geocentric cosmology; that is, it starts by assuming that Earth is stationary and at the centre of the universe. He also said that all the planets are moving in orbits and revolving around the sun.

This geocentric (Earth-centered) model of the solar system was the most popular theory of the solar system窶冱 organization among the Greek philosophers, although it would be standardized and refined by a later astronomer, Ptolemy. their parallax can only be observed with very precise instruments. When Copernicus proposed a heliocentric model—with Earth and the planets all orbiting the Sun—he was compelled to abandon the notion that there is no empty space between the spheres. Ptolemy believed that the heavenly bodies' circular motions were caused by their being attached to unseen revolving solid spheres. He was a mathematician, astronomer, geographer, astrologer, and poet of a single epigram in the Greek Anthology. Claudius Ptolemy was born around 100 A.

Re: Q22 - Copernicus's astronomical system is superior. It was felt there was no need to truly understand them or put them in any kind of order. • Sun is on a separate sphere. Earlier starwatchers had believed the same, and, in fact, Copernicus cited Aristarchus of Samos as an inspiration, but it was Copernicus who brought it to the world of the Renaissance and used hisﾂ�own observations of the movements of the planets to back up his idea.

The Copernican system was a direct challenge to the long-held belief, codifi ed by second-cen-tury astronomer Ptolemy in his book the Almagest, that the sun, moon and stars The Earth revolved on its own axis, and the Moon revolved in its own sphere around the Earth Both had relied, Tycho concluded, on the tables of latitudes and longitudes established by Hipparchus and Ptolemy which involved errors of one degree or more.9 Tycho attributed these Other scientists, including Sir Isaac Newton and Johannes Kepler, seized its importance and were able to learn even more about the ways of the world and the heavens beyond. By questioning the reasoning of the ancients and working from fresh perspectives, which so many were unable or unwilling to try, a revolution was in the making, thanks to them both.

This model became popular in the 16th century because of advances in technology which gained evidence in its favor.
