Detailed explanation-1: -Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula. With the rise of the sun, the remaining material began to clump together. Small particles drew together, bound by the force of gravity, into larger particles, according to the core accretion model.
Detailed explanation-2: -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.
Detailed explanation-3: -A nebula (gas cloud) slowly contracts under the mutual gravity of all of the atoms in the cloud. As the nebula contracts, whatever initial tumbling/rotational motion is increased to conserve angular momentum (just like when a spinning figure skater brings in their arms). The nebula flattens into a disk.
