GENERAL KNOWLEDGE

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: -In 1785, William Herschel proposed such a model based on observation and measurement, leading to scientific acceptance of galactocentrism, a form of heliocentrism with the Sun at the center of the Milky Way.

Detailed explanation-3: -In 1514, Copernicus distributed a handwritten book to his friends that set out his view of the universe. In it, he proposed that the center of the universe was not Earth, but that the sun lay near it.

Detailed explanation-4: -Copernicus’ observations of the heavens were made with the naked eye. He died more than fifty years before Galileo became the first person to study the skies with a telescope. From his observations, Copernicus concluded that every planet, including Earth, revolved around the Sun.
