Today, astronomers believe that the solar system is five billion years old, about halfway through its life. How did the sun and planets form in the first place?
Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust.The cloud collapsed,possibly due to the shockwave of a nearby exploding star,called a supernova .When this dust collapsed,it formed a solar nebula----a spinning,twirling disk of material.
