- According to the solar nebular theory, the earth was formed from a gas of intersellar dust which was rotating.
- Intense pressure and temperature led to the collapse of the core under gravitational pull. The core formed the sun.
- The debris disk accreted to form several planetesimmals from which the earth was derived.
- Most of the solid and denser materials were pulled in closely to sun and they are rock balls called terrestrial planets.
- The outer parts are gas giants.
