The formation of planets in the solar system occurred through a process known as accretion. Here are the steps involved:
1. The initial stage involved the formation of the sun from a massive cloud of gas and dust, known as the solar nebula.
2. As the sun formed, its gravity started pulling in and compressing the surrounding gas and dust.
3. The remaining materials from the sun's formation began clumping together due to gravity. This process is known as accretion. Over time, these clumps of matter grew larger and larger.
4. The solid materials within the solar nebula were forced out of the sun's disc and began cooling down. These solid particles, known as planetesimals, served as building blocks for planets.
5. The planetesimals collided and merged with each other due to gravity, forming larger bodies called protoplanets.
6. As protoplanets continued to collide and accumulate more material, they eventually reached a critical mass and started to exert their own gravitational pull.
7. With enough mass and gravity, the protoplanets further accreted gas and dust from the surrounding solar nebula, becoming the giant planets like Jupiter and Saturn.
8. The remaining rocky material in the inner regions of the solar system formed the terrestrial planets, including Earth, Mercury, Venus, and Mars.
In summary, the planets in the solar system were formed through the accretion of solid materials from the sun's formation, along with the accumulation of gas and dust around protoplanets.
