Centuries ago, humans believed the Earth was the center of the universe, with the Sun and all other celestial bodies revolving around it. However, Nicolaus Copernicus proposed a groundbreaking theory in the 16th century - the heliocentric model, positioning the Sun at the center and the Earth and other planets orbiting around it. This model laid the foundation for our modern understanding of the Solar System. Our Solar System was formed about 4.6 billion years ago from a giant molecular cloud. At its heart, the Sun, a burning sphere of gas, holds the System together with its immense gravitational pull. Orbiting it are eight diverse planets, each with unique characteristics. The terrestrial planets, Mercury, Venus, Earth, and Mars, are dense and rocky. Beyond them lie the gas giants, Jupiter and Saturn, followed by the ice giants, Uranus and Neptune. Beyond the planets are millions of asteroids, comet nuclei, and meteoroids, collectively forming the asteroid belt, Kuiper belt, and Oort cloud. Dwarf planets like Pluto also reside here. Each celestial body in our Solar System, no matter how small, conveys its story about the universe. With the advent of technology, our understanding of these cosmic entities continues to grow. Explorations like the Mars Rover and Voyager missions have only added to our knowledge and raised exciting prospects.
