They believe the planets formed from a disc of gas and dust called a "protoplanetary disc".
Nebular model
Yes. As a new star is forming it is surrounded by a disk of gas and dust called a protoplanetary disk. Planets, asteroids, and comets all form from this disk.
well probably because when the solar system formed, the sunwas made of gas and dust, the remaining gas and dust not used on the sun became the planets, most likely during the formation of the planets their was only enough dust to make 9 planets and a few million asteroids
The planets formed from a disk of gas and dust that surrounded the sun as it formed. This gas and dust clumped together to form the solar system. Two planets cannot occupy orbits that are too close together. If they do, interactions through gravity will either cause them to collide or get moved to different orbits.
The disk of dust and gas that formed the Sun and planets is known as the solar nebula.The dense concentration of gas at the center of this rotating disk eventually became the Sun.

From rocks, ice, dust, and gas. This process is called Accretion.
Nebular model
Planets (and stars) were formed out of dust and gas. That had a rotation to it which does not go away (this is known as the Conservation of Angular Momentum).

Inertia
It is from interstellar gas and dust that we all came. The stars, planets, asteroids, and comets all came from clouds of gas and dust. As far as OUR gas and dust NOW, nothing much is produced. Its mostly all used up in the making of us.
