SOLAR SYSTEM

Detailed explanation-1: -Galileo’s discoveries about the Moon, Jupiter’s moons, Venus, and sunspots supported the idea that the Sun-not the Earth-was the center of the Universe, as was commonly believed at the time.

Detailed explanation-2: -Before the 17th century, people generally believed that Earth was at the center of the universe. Galileo, however, was not afraid to challenge existing beliefs when he published his work in support of the Sun-centered, or heliocentric, Copernican theory.

Detailed explanation-3: -The Sun is the only star in our solar system. It is the center of our solar system, and its gravity holds the solar system together. Everything in our solar system revolves around it – the planets, asteroids, comets, and tiny bits of space debris.

Detailed explanation-4: -The Sun is the center of the solar system. What is the Sun? Earth’s Sun may seem different to us, but it is a star like all the other stars located outside the solar system.

Detailed explanation-5: -Nicolaus Copernicus proposed his theory that the planets revolved around the sun in the 1500s, when most people believed that Earth was the center of the universe.

Detailed explanation-6: -Galileo continued his study of astronomy and became more and more convinced that all planets revolved around the Sun. In 1632, he published a book that stated, among other things, that the heliocentric theory of Copernicus was correct.

Detailed explanation-7: -The discoveries that Galileo made using his telescopes helped to prove that Sun was the centre of the Solar System and not the Earth. His observations strongly supported a Sun-centred model known as the Heliocentric model, previously suggested by astronomers like Nicolaus Copernicus.
