GENERAL KNOWLEDGE

Detailed explanation-1: -In 1543, Nicolaus Copernicus detailed his radical theory of the Universe in which the Earth, along with the other planets, rotated around the Sun. His theory took more than a century to become widely accepted.

Detailed explanation-2: -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-3: -Copernican system, in astronomy, model of the solar system centred on the Sun, with Earth and other planets moving around it, formulated by Nicolaus Copernicus, and published in 1543.

Detailed explanation-4: -In 1610 Galileo Galilei observed with his telescope that Venus showed phases, despite remaining near the Sun in Earth’s sky (first image). This proved that it orbits the Sun and not Earth, as predicted by Copernicus’s heliocentric model and disproved the then conventional geocentric model (second image).
