• Answer:

  It is not known precisely what mechanism caused the precursor of the solar system, a gaseous nebulae, to form into the Sun and its attendant accretion disc. It may have been shockwaves from a nearby supernova, or simple gravitational collapse due to a threshold density. Whatever the cause, when enough density gathered in the center of the gas cloud, it ignited to become the Sun. The resulting heat banished volatiles (materials with low melting points) to the outer solar system, while leaving rocky bodies, like the Earth, Mercury, Venus, and Mars, in the inner solar system, where they could grow.
