The Solar System, a term we have all heard and talked about since school, is a system largely formed and held together by the star we call Sun, whose massive gravitational force keeps millions of objects revolving around it, in both stable and less stable orbits. Our sun, among the billions of stars in our Milky Way, is located about 27,000 light years from its centre. The Milky Way is a spiral galaxy, and our solar system is situated in one arm of the galaxy, called the Orion.
The Sun along with its planets revolves around the centre of the Milky Way, and every 230 million or so years it is thought that we complete a whole revolution. So every day we wake up, we pass a new region in our Galaxy that has not been seen in a very long time. The sun accounts for about 99% of the total weight of the solar system; it was formed around 4.6 billion years ago from hot dense gas and dust rotating and coming together, due to the strong gravitational forces....
