The Solar System is believed to have formed from the gravitational collapse of a giant molecular cloud approximately 4.6 billion years ago.
This collapse began a series of events that eventually led to the formation of the Sun, planets, moons, comets, and asteroids.
The collapse of the giant molecular cloud created a protoplanetary disk, a spinning disk of dust and gas, which surrounded the Sun.
The dust and gas contained within the protoplanetary disk began to clump together due to gravitational attraction....
and this clumping caused the dust and gas to form into planets, moons, comets and other small bodies.
Over time, the planets and other bodies in the Solar System moved and collided with each other, forming the planets and moons we see today.
The planets in the Solar System can be divided into two categories: the rocky planets and the gas giants.
The rocky planets, which include Mercury, Venus, Earth, and Mars, are believed to have formed from the accumulation of smaller pieces of material.
These pieces of material collided with each other, forming larger and larger pieces until they eventually became the rocky planets we see today.
The gas giants, which include Jupiter, Saturn, Uranus, and Neptune, are believed to have formed from the accumulation of gas and dust.
