WORLD HISTORY

Detailed explanation-1: -Nicolaus Copernicus was a Polish astronomer and mathematician known as the father of modern astronomy. He was the first European scientist to propose that Earth and other planets revolve around the sun, the heliocentric theory of the solar system.

Detailed explanation-2: -The Polish astronomer, Nicholas Copernicus (∼1540), proposed the heliocentric theory. (Actually, Aristarchus (∼250 B.C) had promoted the heliocentric theory but it was not popular in his time.) Copernicus adopted a heliocentric view because it better explained the motions of the heavens mathematically.

Detailed explanation-3: -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.

Detailed explanation-4: -Heliocentrism is the astronomical model in which the Earth and planets revolve around the Sun at the center of the Solar System. Historically, heliocentrism was opposed to geocentrism, which placed the Earth at the center. In India, Aryabhata was the first to propose the theory that the earth revolves around the sun.

Detailed explanation-5: -From his observations, Copernicus concluded that every planet, including Earth, revolved around the Sun. He also determined that the Earth rotates daily on its axis and that the Earth’s motion affected what people saw in the heavens.

Detailed explanation-6: -The first person known to have proposed a heliocentric system was Aristarchus of Samos ( c. 270 BC). Like his contemporary Eratosthenes, Aristarchus calculated the size of the Earth and measured the sizes and distances of the Sun and Moon.
