1. Nebula - dust gas
2. Spins - conservation of angular momentum
3. Condensing and contracting - getting smaller, thus spins faster - generating heat
4. Gas and Dust is becoming very condensed in the middle, generating lots of heat - this is the protostar!
5. Large dense clumps of gas and dust around the proto star due to gravity attracting the particles together are forming to become protoplanets
6. Terrestrial planets are able to form closer to the protostar because of their higher temperature of solidity, opposed to the gas planets
7. Once the protostar is so condensed, nuclear fusion happens, and emits radiation and helium. This is when the protostar became the "sun"
