SOLAR SYSTEM

Detailed explanation-1: -This proved that it orbits the Sun and not Earth, as predicted by Copernicus’s heliocentric model, and disproved Ptolemy’s geocentric model (second image).

Detailed explanation-2: -Copernicus rejected the Ptolemaic theory basically because he found it too contrived, reasoning that there had to be a simpler hypothesis which could explain everything to his satisfaction.

Detailed explanation-3: -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.

Detailed explanation-4: -Copernican heliocentrism is the astronomical model developed by Nicolaus Copernicus and published in 1543. This model positioned the Sun at the center of the Universe, motionless, with Earth and the other planets orbiting around it in circular paths, modified by epicycles, and at uniform speeds.

Detailed explanation-5: -This problem so perplexed the Polish priest-astronomer Nicolaus Copernicus (1473-1543) that he eventually decided to reject the geocentric model, and revive the heliocentric model of Aristarchus.

Detailed explanation-6: -Nicolaus Copernicus was an astronomer who proposed a heliocentric system, that the planets orbit around the Sun; that Earth is a planet which, besides orbiting the Sun annually, also turns once daily on its own axis; and that very slow changes in the direction of this axis account for the precession of the equinoxes.
