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 4.6 billion years ago when a nearby star exploded, sending waves of energy out into space. When hit by a wave, one big cloud of stellar dust and gas, called a nebula, collapsed into a spinning disk. That disk pulled more dust and gases into the center due to a force called gravity.
Detailed explanation-3: -A star’s life is a constant struggle against the force of gravity. Gravity constantly works to try and cause the star to collapse. The star’s core, however is very hot which creates pressure within the gas. This pressure counteracts the force of gravity, putting the star into what is called hydrostatic equilibrium.
