Answer:

Accretion

Explanation:

Accretion is the process by which there is an accumulation of particles into a bigger object by attracting more mass by gravitational force into an accretion disk. This is one of the first steps in the formation of our solar system. There was a collapse of a gas cloud which resulted in most of the mass collecting in the center leading to the formation of the sun and the rest spread out forming the planets.
