Detailed explanation-1: -Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula.
Detailed explanation-2: -The steps to nebular theory go as follows. Nebula becomes a solar nebula as a region within the cloud of gas and dust condenses into a core and forms a protostar. The condensing material could have been caused by a nearby supernova shockwave. The material surrounding the protostar collapses into an accretion disk.
Detailed explanation-3: -The nebular hypothesis is the idea that a spinning cloud of dust made of mostly light elements, called a nebula, flattened into a protoplanetary disk, and became a solar system consisting of a star with orbiting planets [12].
