How was our solar system formed?
What is 4.6 billion years ago it started as a cloud of dust and gas. The shockwaves from a possible supernova or exploding star caused the cloud to compress which resulted in a flat, spinning disc of heated material. The heated material in the cloud triggered nuclear fusion forming the sun. Material not used to make the Sun began to cluster together to form asteroids, comets, planets and moons. Eventually only rocky materials could survive close to the sun so objects that were gaseous and icy successfully clustered further away, forming the solar system we will in today.
